In scientific calculations on the course, g represents the acceleration produced in a falling object by the effects of gravity.
For example, to calculate the weight of a 10 tonne machine, we convert the 10 tonne to the base unit of kilogrammes, 10,000 Kg. This is the mass of the vehicle. To calculate the weight, we use the following formula:
W = m x g
W = 10,000 x 9.81
W = 98,100 Newtons, or 98.1KN
In Plant Vehicle electronics, transistors are used for switching and amplification.
The switching action involves using the base/emitter circuit to switch on and off the collector/emitter circuit.
A second use of the transistor is amplification. It can take a very small input at the base/emitter and amplify it at the collector/emitter circuit. This larger signal can then be used to switch on and off 30 amp relays, or signal the ECU.
The amount by which the base/emitter signal is amplified is said to be the gain of the transistor. For example, the BC109 transistor commonly used on the course has a gain (hFE) of between 200 and 800, meaning that the collector/emitter current can be between 200 and 800 times greater than the base/emitter current.
A galvanometer is an extremely sensitive instrument for detecting and measuring electrical current.
A galvanometer must always be connected in series in a circuit, and should only be used to measure very small currents.
It is important for the apprentice CP Fitter to have a basic understanding of how these factors are inter-related.
Why is it important for the apprentice to understand these laws?
Gaskets are used to join surfaces together, whenever this joint is required to be leak-proof

Gasoline Direct Injection. As the name suggests, the fuel is injected directly into the combustion chamber of the engine (not into the inlet manifold).
In the wiring diagrams in AutoData, the abbreviations for colours are in German. Here are some translations:
A gear pump uses the meshing and un-meshing of gears to move liquids like engine oil and hydraulic oil.
The number of turns needed at the input shaft in order to produce one full turn of the output shaft. For example, a ratio of 4:1 means that four full turns are required of the input shaft in order to prodcue one full turn of the output shaft. A ratio of 0.9:1 is called an overdrive. This means that less than one full turn of the input produces one full turn of the output shaft. This is the sort of ratio used in 5th gear in cars.
