Please could I have some help with the following question:(adsbygoogle = window.adsbygoogle || []).push({});

A driver wheel, which runs a drive belt has a diameter of 600mm and can run at a maximum speed of 750rpm. If the belt has a static coefficient of friction of 0.9 and a dynamic coefficient of friction of 0.87, calculate:

a) The angular velocity (Omega) of the wheel in rad/s.

b)The linear velocity of the wheel.

c) If the normal force between the belt and the driver wheel is 750N, what will be the maximum force which can be transmitted when the belt is running at a constant speed? Explain your answer.

d) If the speed of the wheel is reduced to 300rpm, over a period of 10s, calaulate the angular retardation.

Thanks for any help,

Chris
