The solid steel shaft carries the torques T1= 1200 Nm and T2=750 N m. Using L1=L2=2.5 m and G = 83 GPa, determine:
a. draw a diagram using a double headed arrows showing the torque in each segment
b. determine the shear stresses in each segment and the angle of rotation of the free end if the diameter is 100 mm.
c. the smallest allowable diameter of the shaft if the shear stress is limited to 60 MPa and the angle of rotation of the free end is not to exceed 4^0.
