Part 2:

a) You are investigating voltage, v, across a diode in the conveyor system. The current, i, through the diode is given by 

where I is the reverse saturation current, η is the emission coefficient and T is the temperature.

Evaluate v when η=2, T =T Kelvin, I = 0.1 μAmps and i =5 mAmps.

b) The drive system for the drum used to in the first part is made up of an open belt which passes over the drum and drive wheel. The drive wheel has a diameter of 320mm respectively and the distance between centres is D mm. 

You have been asked to determine the length of the belt, using trigonometric techniques, assuming the belt is in tension.

c) The marine engines are tested in a water tank depth 1.6m (d). The wave length of the waves λ is measured to be L meters. And the velocity of the waves is 5.7m/s, calculate the acceleration A
