PROBLEM The diameter of two pulleys are (0.3m)and (0.2m), center distance (1m).if we use open belt drive. Determine: 1- the length of V-belt (2ß = 60°). 2- the contact angle between belt and smaller pulley. 3- the horse power, if the smaller pulley turn with speed (400r.p.m) and the tension force in tight side (T1=900N), coefficient of friction ų=0.3 4- the speed of large pulley.

A conical clutch has an included angle of 120°, a coefficient of friction of 0.4, and outer and inner diameters of 85mm and 18mm respectively. Using both the uniform wear theory and the uniform pressure theory, calculate the force required to press the two halves together if it is to transmit 300W at 750rev/min. The uniform wear theory and the uniform pressure theory deliver different values for torque in the same system. Which theory would be preferred in practice for use in calculations involving a friction clutch? Give reasons for your choice.
Two parallel shafts whose centre lines are ‘5’ m apart, are connected by an open belt drive. The diameter of the larger pulley is ‘3’ m and that of smaller pulley ‘3’ m. The initial tension in the belt when stationary is ‘4’ kN. The coefficient of friction between the belt and the pulley is 0.3. Calculate the power transmitted, when the smaller pulley rotates at ‘700’ r.p.m. and length of the belt.
