Thirty horsepower is supplied to the 30in. sprocket by means of a chain drive as shown in Figure below. Twenty horsepower is taken off at the 24in. pulley which weighs 1000lb and 10hp is taken off at the 8in. crank. The force in the chain on the tight side is represented by T c ​ The tension in the slack side is so small that it can be neglected. The ratio of the tensions in the belt is 4:1. The shaft is rotating at 300rpm. The loads are applied with moderate shock, C m ​ =2 and C t ​ =1.5 determine the size of shaft necessary if S c ​ (allowable) 8000psi. It is assumed that the sprocket and pulley are keyed to the shaft.

Please briefly explain why you feel this question should be reported.
