A short 61 mm Φ shaft transmits 120 Hp. Compute the linear speed of a pulley 55 cm Φ mounted on the shaft.

The shaft is subjected to the axial force of 40 kN. Determine the average bearing stress acting on the collar C and the normal stress in the shaft. 

A shaft is subjected to a maximum torque of 14 KN-m and a maximum bending moment of 10 KN- m at 
a particular section. Determine the diameter of the shaft according to maximum shear stress theory if the 
elastic limit in simple tension is 180 MPa
