Free, open source operating system. Unlike windows, linux can be downloaded free of charge from the world wide web. It is open source, meaning the code that drives the operating system is open to all. Anyone can download the os to their computer and modify it as they see fit.

Pressure is defined as the force applied to a unit area of a surface.
:
A vertical force exerted by a mass as a result of gravity.
:
Something that occupies space and can be perceived by one or more senses.

The word Moodle is an acronym for Modular Object-Oriented Dynamic Learning Environment.

Electrical device used in heavy duty automotive circuits. There are two circuits in a relay: one is a light duty switching circuit which controls a different heavy duty circuit. For example, in a headlamp circuit, the light duty switching circuit is controlled by the headlamp switch. This in turn controls the heavy duty supply that serves the headlamps. The main advantage of this arrangement is that the heavier wires that serve the headlamps do not have to be run into the cab and up to the driver's dashboard. Only the light duty switching wires have to go here. The heavy duty wires can go directly from the live source, to the relay (terminal 30), out of the relay (terminal 87) and off to feed the load-in this case, the headlamps.

  • Data can be stored on the memory stick.
  • Memory Sticks hold varying amounts of data from 256Mb up to 2Gb
  • Memory Sticks connect to the USB port.
  • You must inform the computer when you are about to disconnect the memory stick from the USB port. You do this by double clicking the symbol shown below. This symbol is displayed in the system tray once a memory stick is connected to a computer:
    USB stop in system tray. 
  • If you fail to stop the device before removing it, you run the serious risk of corrupting any data on that device.

The reserve capacity of a battery is the time in minutes for which a battery is capable of supplying 25 amps at 25oC ambient temperature in the event of the failure of the vehicle charging system. This time is measured until individual cell voltage drops below 1.75 volts.
For example, the average car battery has a reserve capacity of approximately 60 minutes. This means that, supposing the alternator failed, and the ambient temperature was 25oC, the battery could continue to supply 25 amps for 60 minutes before individual cell voltage in that battery dropped to below the useful minimum value of 1.75 volts.

Ambient simply means surrounding. For example, ambient temperature is the surrounding temperature.

Pascal is the basic SI unit of pressure. It is named after the French mathematician, philosopher and physicist, Blaise Pascal.

The Pascal is the basic unit of pressure:
1 Newton per square metre, or 1N/m2.

This unit is very small and is of little practical use in automotive engineering, so we use kiloPascals instead.
1,000 Pascals = 1 kiloPascal.

100 kPa = 1 bar. (100kN/m2)
