A leather belt is required to transmit 7.5 Kw of power from a pulley 1.2m in diameter at 250 rpm. The lap angle (contact angle between small pulley and belt) is 165o and the coefficient of friction of friction between the belt and the pulley is 0.3. If the safe working stress for the leather belt is 1.5 MPa, density of leather 1 Mg/m3 and thickness of belt 10 mm, determine the tension in the both (tight and slack) side and width of the belt taking centrifugal tension into account
