Question:

Two pulley, one 450 mm diameter and the other 200 mm diameter are on

parallel shafts 1.95 m apart and are connected by a crossed belt. Find the

length of the belt required and the angle of contact between the belt and each

pulley.

What power can be transmitted by the belt when the larger pulley rotates at

200 rpm, if the maximum permissible tension in the belt is 1 kN and the

co-efficient of friction between the belt and pulley is 0.25 ?
