Vehicle Design Transmissions Part 1 Dr. Alasdair Cairns Content • Transmission fundamentals – Principles of gears (revision) – Road load losses • Gear ratio optimisation – Performance – Fuel economy Transmissions – Overview Why do we need a gearbox in a road car? Transmissions – Practical Use Seven practical reasons why a gearbox is required: 1. To increase tractive effort when the vehicle is moved from rest 2. To improve hill climbing or descending ability

Title: Measuring the speed of sound. Research question: How to determine the speed of sound by using the relationship between the frequency of the signal generator‚ f and the length of air column in the tube‚ l . Variables: Manipulated | Frequency of the signal generator‚ f | Use different frequency of signal generator which are 1000Hz‚ 1400Hz‚ 1800Hz‚ 2000Hz‚ 2500Hz‚ 3000Hz and 3600Hz. | Responding | Length of air column in the tube‚ l (±0.5cm) | Measure the

cabling medium are factors that prevent the accuracy of transmitted data to be intact. For these reasons different encoding methods exist. An example is when 2 wires are used to transmit music data to a speaker Digital signals don’t always have to be carried over to the receiving end by electricity‚ light can also be used for digital communication. Fibre Optics use light to transmit data through optical fibre within the cable. The strength of the light ray can also be a determining factor to

the following situation and answer the following questions. A circular track has a circumference of 3140m with AB as one of its diameter. A man riding a scooter moves from A to B along the circular path with a uniform speed of 10 m/s. a) Distance covered by the man b) Displacement of the man c) Time taken by the man in reaching from A to B. 2. A car starting from rest moves with a uniform acceleration of 0.1 m/s2 for 2 minutes. Find the speed acquired by the car. 3. A ship is moving at a speed of

Automatic transmission modes[edit] Conventionally‚ in order to select the transmission operating mode‚ the driver moves a selection lever located either on the steering column or on the floor (as with a manual on the floor‚ except that most automatic selectors on the floor do not move in the same type of pattern as a manual lever; most automatic levers only move vertically). In order to select modes‚ or to manually select specific gear ratios‚ the driver must push a button in (called the shift lock

Speed of Light Determining the speed of light is something that has been a very long and trying process. No one scientist could determine such a thing. Galileo was the first noted scientist to attempt experimentation on the speed of light. Other famous scientist‚ such as‚ Roemer‚ Foucault‚ Fizeau‚ Michelson‚ and Einstein added their own discoveries to the collage of information gathered through the years. Every scientist performed their experiments differently based on the knowledge and ability
