Question

Transcribed Image Text:Power is transmitted between two shafts by a V-belt whose mass is 0.9 kg/m
length. The maximum permissible tension in the belt is limited to 2.2 kN. The angle of
lap is 170° and the groove angle 45°. If the coefficient of friction between the belt
and pulleys is 0.17, find : 1. velocity of the belt for maximum power; and 2. power
transmitted at this velocity.
Note: Sketch the belt drive system for both parts and label the given data on it.
