1. Calculate the maximum shear stress acting at the point of load application on hollow shaft AB Fig.1. (10pst) 2. An electric motor "M" supplied a power of 110kW to a machine "m", through a solid shaft whose section is circular. The material has a shear modulus G=70 GPa and an allowable shear stress t = 85 MPa. a. Calculate the minimum diameter d of the shaft which turns at maximum speed of 600 rpm. And also calculate the angle of twist of the shaft transmission. Fig.2 b. If the shaft is rotated at a lower speed (300 rpm) maintaining the same power, should we reduce or increase its diameter?
