Automatic vs Manual Transmission
Which is better: Manual or Automatic transmission? This debate has been present for the last seven decades. Manual and automatic transmissions are completely different technologies, which use different configurations and principles. One is based on a simple gear pair, while the other is based on a planetary gear set. One uses a torque convertor, while the other uses a clutch pack. We will do a logical comparison of these technologies in this video. We thank our patrons for making LE's educational service sustainable.

2 The Principle of the Electron Microscope
How to Make a Microscope, Chapter 2 Unlike the optical microscope, the scanning electron microscope uses accelerated electrons in a vacuum to act as light to view the sample. An electron is the negatively charged particle of an atom orbiting around a nucleus. It can be released by heat or an electric field. Electrons are 2,000 times lighter than the smallest atom, thus they can be easily stopped or diverted when striking materials. Because electrons move freely only in a vacuum, there must be a vacuum in the entire column. To achieve this state, vacuum pumps are used along with various levels of vacuum. Dozens of millions to billions of electrons hit the sample per second. Electromagnetic lenses then focus the beam on the examined sample in an optimal way. During its journey, the electron beam passes through a number of apertures with various diameters, which stop electrons undesirable for creating an image. The electrons can either scan the sample step by step or go through the sample to show its inner structure, giving us the distinction between a scanning and a transmission electron microscope. Modern electron microscopes not only display, but also analyze, measure, and modify in 2D, 3D, and 4D.
What is WDM (Wavelength Division Multiplexer)? - FO4SALE.COM
http://www.fiberoptics4sale.com WDM stands for Wavelength Division Multiplexing. WDM is the most important and most popular method to increase the capacity of a single strand of fiber. As we all have learned from elementary school science, a white light beam can be separated into individual colored light beams by a prism, as shown in this picture. Vice versa, individual colored light beams can also be combined into a single white light beam by the prism, that is if we use the prism in the reverse direction. WDM uses this same idea. Traditionally, only one colored light was used on a single strand of fiber to carry the information, such as 1550nm light. However, starting from the early 1990s, the Internet boom pushed service providers to find a method to increase the capacity on their network in the most economical way. That is when WDM devices were invented. As shown in the right side picture, in a WDM system, many different colored lights are combined by a WDM multiplexing device and put into a single strand of fiber, each color is called a channel. On the receiving side, each color is separated into its own channel by a WDM de-multiplexing device. It shows that a single fiber's capacity is increased by 40 times with a 40 channel WDM. The beauty of WDM is that you only need to upgrade the end equipment, no need to dig up trenches to bury more fibers, which is much more costly. So how are WDM devices made? This picture shows a 3 channel WDM device based on thin-film filters. Thin-film filters are a piece of flat surface glass with optical coatings on it. The optical coatings are designed to pass and reflect certain colored lights. This is a de-multiplexing WDM device, which means that it separates combined colored lights from a single fiber into separate individual fibers. But if used in the reverse direction, it can also combine different colored lights from individual fibers into a single fiber. As shown, three colored lights, which are 1510nm, 1530nm and 1570nm, come from a single strand of fiber 1. The GRIN lens collimates the light so it won't diverge into a large un-controlled beam. Filter 1 is designed to pass 1530nm and 1510nm, but reflect 1570nm. So when the light hits filter 1, 1570nm is reflected and re-focused into fiber 2 by the GRIN lens. Now the light has 1530nm and 1510nm in it, and it keeps going until it hits filter 2. Filter 2 is designed to pass 1510nm but reflect 1530nm, so 1510nm light passes and is focused into fiber 3 by the 2nd GRIN lens. On the other hand, 1530nm light is reflected by filter 2, passes filter 1 again, and is focused into fiber 4 by the 1st GRIN lens. Why isn't 1530nm focused into fiber 2? That is because the filters have a thickness, so there is a offset on the vertical direction. We just talked about a 3 channel WDM device. Thin-film filter based WDMs can be cascaded together to get higher channel counts, such as 4, 8, 16, 32 channels. The right side picture shows a 8 channel WDM device. The left picture shows how it's made by cascading several WDMs together. In additional to thin-film filter based WDMs, there are also fused fiber based WDMs, Arrayed Waveguide Grating based WDMs, Interleaver based WDMs, etc. They use different mechanisms to separate the colored lights. So there you have it. Please don't forget to visit http://www.fiberoptics4sale.com for more free fiber optic tutorials. I will see you in the next video!

Optical Fibres in Communication: Covers all Important Points about Optical Fibre [HD]
For More Detailed Knowledge and Lots of Interesting Stuff, You Should Visit My BLOG At Least Once- https://www.engineeringmadeeasypro.com/ This lecture on optical fibre includes: 1- What is an optical fibre? 2- Structure and working of the optical fibre 3- optical fibre communication process 4- Types of optical fibers (Single Mode Fiber and Multi Mode Fibre) 5- Benefits of optical fibers 6-Losses in optical fibre 7-Dispersion in optical fibre 1.What is an Optical Fibre? For more details you can visit my BLOG- http://www.engineeringmadeeasypro.com/ An optical fiber is a flexible and transparent fiber which is made by drawing glass (silica) or plastic. Optical fiber has a diameter slightly thicker than that of a human hair. 2.Structure and Working of the Optical Fibre Optical fibers are made of glass or plastic. Most optical fibers used in communication have diameter of 0.25 mm to 0.5 mm including outer coating. Optical Fibre communication takes place between 0.8 micrometer to 1.7 micrometer of wavelength of electromagnetic spectrum. Optical fibres have a transparent core which is surrounded by a transparent cladding and the cladding has a protective covering over it. The image given below explains the concept of Total Internal Reflection (TIR) which is the phenomenon responsible for propagation of light inside the optical fibre. Based on the refractive index profile, there are two categories of optical fibres- #Step Index Optical Fibres #Graded Index Optical Fibres In step index fibres, the refractive index profile makes a step change at the core-cladding interface. In step index fibre if core has refractive index n1 and cladding has refractive index n2, then this condition holds- n1 greater than n2 And this is necessary condition for Total Internal Reflection (TIR) in the optical fibre. While the graded index fibres don't have a constant refractive index in the core but the refractive index of the core decreases with increasing radial distance from the core axis. It has maximum value of refractive index at the core axis that decreases as we move away from the core axis and becomes constant in the cladding. The light rays travel inside the core by the phenomena of total internal reflection. Since the core has higher refractive index (n1) than that of cladding (n2) So when the light rays fall on the core-cladding interface (moves from denser to rarer medium), it returns back into the core. But for the Total Internal Reflection (TIR) to take place, it is necessary for the light rays to have incidence angle greater than the critical angle while moving from denser to rarer medium (core to cladding). 3.Optical Fiber Communication Process Message that we want to transmit maybe non-electrical in nature (audio signal), so first of all it needs to be converted into electrical form using transducers. Now the message converted into electrical form modulates an optical source. Ex. LASER or LED. After this the light rays containing message travel through the optical fiber by the phenomena of total internal reflection. Due to total internal reflection the energy loss is negligible inside the fiber while travelling. Now at the receiving end, photodetectors like photodiodes or phototransistors etc, are used to convert the light signal back into electrical signal. Then the original message signal is retrieved from this electrical signal. 4.Types of Optical Fibres (Based on Modes of Propagation) There are two types of optical fibres based on modes of propagation - #Single Mode fibres (SMF) #MultiMode fibres (MMF) As clear by the name itself, the single mode fibres support only one propagation path, since they have very small diameter. While multimode fibres can support many propagation paths or transverse modes as they have larger diameter. Single mode fibres are used for long distance communication while multimode fibres for short distance communication. Single mode fibre provide greatest transmission bandwidth and lowest losses in communication. 5.Benefits of Optical Fibres #Energy loss is negligible inside the optical fibres while propagation due to total internal reflection. #Optical fibres provide very large potential bandwidth (since optical communication takes place at very high frequency. #Optical fibres have small size, are lightweight and very flexible. #Optical fibres provide electrical isolation and are shock resistant. Since inside the fibre, light propagates; not any electric current. #Optical fibers provide high degree of signal security since these fibres do not radiat #Optical fibres are easy to maintain and the communication system is reliable. 6.Losses in Optical Fibres. These losses are the following- #Material absorption #Linear and nonlinear scattering #Fibre bend losses 7.Dispersion in optical fibres When light rays travel through the fiber, the phenomena of dispersion (broadening of transmitted light pulses), The dispersion is of two types- #Intermodal Dispersion #Intramodal Dispersion

DSG Transmission - Explained
What is a DSG transmission? How does a direct shift gearbox work? A DSG transmission is a dual clutch transmission used by Volkswagen. A DSG uses two wet, multi-plate clutches to activate separate drive shafts which send torque via the even or odd gear sets. Because the gear sets are on separate shafts, this allows for preselecting the next gear, allowing for nearly instantaneous gearshifts without a total loss in torque. DSG tranmissions operate a lot like manual transmissions, but they are electronically controlled and thus the gear selection can be either automatic or manual, but does not require the use of a clutch pedal as this is all activated automatically.

This is the first of a five part series sponsored by Formula E, who I’ve partnered with to talk about the engineering behind electric cars. I had the opportunity to get behind the scenes at the New York City E-Prix, and was able to chat with team principals, hang out in the engineering rooms during qualifying, and even learn from this year’s champion, Lucas di Grassi. So why do electric cars use just a single gear, rather than using traditional transmissions like you’d find paired with internal combustion engines? Electric motors can get away without numerous gears because they are high revving, remain fairly efficient across a very broad rev range, and produce a great amount of torque at low RPM.

The D-Drive Infinitely Variable Geared Transmission
This brain-bending invention could be the holy grail of transmission technology - it allows you to smoothly move through gear ratios from top gear all the way through neutral and into reverse without ever disengaging the engine. Plus, there's no friction drive component, so the power is always transmitted through gear teeth - there's never any slip or friction losses. In fact, the D-Drive's main difficulty is that it's so damn hard to understand that people don't really know what to do with it. So here's a close-up look, which will hopefully get a few people thinking.

Differential steering From Wikipedia, the free encyclopedia https://en.wikipedia.org/wiki/Differential_steering Differential steering is the means of steering a land vehicle by applying more or less drive torque to one side of the vehicle than the other. Differential steering is the primary means of steering tracked vehicles, such as tanks and bulldozers, is also used in certain wheeled vehicles commonly known as skid-steer, and even implemented in some automobiles, where it is called torque vectoring, to augment steering by changing wheel direction relative to the vehicle. Differential steering is distinct from torque steer, which is usually considered a negative side effect of drive-train design choices. #DifferentialSteering

principles of AM radio transmission and reception (electronic demo circuit)
Correction to the video: when I say "rectified" I mean "received" and the emitter resistor is not 270 K but 270 Ohms (!). The video shows an AM transmitter and crystal receiver with a germanium diode as rectifier. The modulation is realised by modulating the supply current (voltage) to the oscillator. This means that the strength from the current trough the oscillator depends on the audio sound (or whatever signal) send to the base from the modulating transistor in the supply lead. More radio and other circuits in my books on the Lulu website or via booksellers, author Ko Tilman. In my book "Retro Radio" (Dutch text!) issued by Elektor International Media in the Netherlands (website Elektor) you can find more radio circuits (schematics), especially simple superheterodyne Shortwave radios from 2 MHz up to 17 MHz.

Cars: engine power and transmission - 3D animation
The physical principles behind car gears. Visit my homepage, http://www.zutopedia.com/udia.html, or read about my latest book http://www.zutopedia.com This video offers an unusual perspective to the relation between engine power, RPM and acceleration. Some comments: 1) Torque - a gear of radius R that exerts force F is said to have a torque of T=R*F. Engines do not produce force per se, but torque. So if the engine produces a torque of T, and that is transmitted unchanged to a gear of radius R, you a get a force of T/R. The video offers an alternative view, where the relation between RPM, power and accelartion is explained without torques. See more about torques in this video: http://www.youtube.com/watch?v=Sm4pV3xyJRE 2) Efficiency - this video assumes and ideal world with 100% efficiency. No energy is wasted on friction or any other mechanical losses. 3) Another simplifying assumption is that the engine produces a constant torque, and thus a constant force. As mentioned in one of the comments in the end, this is not the case with real engines. In most engines the torque rises as RPM rises, peaks at some RPM, and then starts to fall. Because of that the power does not steadily increase with RPM. It increases in the beginning, and continues to increase a little bit after the torque peaks. Then as the torque starts to dimish significantly, the power reduces as well. 4) Measurments - here are the measurments used in the simulation: 16 teeth gear radius: 18cm = 0.6 ft Force exerted by this gear: 196N = 44.1 lb Car wheel radius: 21cm=0.7 ft Car weight: 352kg = 775 lb 5) The car wheels are slightly bigger than the 16-teeth gear, and this is adds up to the gear ratio effect. In the first car, for example, while the transmission box has a gear ratio of 1:1, the larger wheels cause an overall gear ratio of 1.18:1. This can be seen at time 2:25, where the wheel's power visualization is slightly elongated (a bit more speed and a bit less force).

#143: Transmission Line Terminations for Digital and RF signals - Intro/Tutorial
An introduction to why and when terminations are needed for transmission lines in both high speed digital applications and RF applications. 50 ohm termination examples are given, but the principles apply for other line impedances as well. The basic operating principles of signal propagation down a transmission line and the effects of reflections coming from improperly terminated are covered. Examples for digital-like signals as well as RF signals are given. A description and examples of what is meant by Standing Waves is also given. As a bonus, the properties of quarter wavelength transmission lines in RF applications is also presented. Notes from the video can be found here: http://www.qsl.net/w/w2aew//youtube/Transmission_Line_Terminations_Digital_RF.pdf
