question
A (1/4) in. thick double leather belt is used on a cast steel pulley 50 in. in diameter which rotates at 1000 rpm and transmits 100 hp. Calculate the belt width using the following data: Coefficient of friction between cast-steel and leather = 0.40. Safe stress for belting = 300 psi Joint efficiency = 70 percent.
