Question

Provide a very clear and complete solution as well as diagram.

A pulley 600 mm in diameter transmits 40 KW at 500 rpm. The arc of contact between the belt and pulley is 144 degrees, the coefficient of friction between belt and pulley is 0.15 and the safe working stress of the belt
is 2.1 Mpa. Determine the belt tension ratio, neglecting the effect of centrifugal force.
