Problem #1. The 60-mm diameter shaft is subjected to torques as shown. If the applied allowable torque T in Kn-m. Check if the shaft satisfies the allowable shear stress and angle of twist limitations. The allow ble shear stress is 80 MPa and the angle of twist of disk A relative to disk C is limited to 0.06 rad. The shaft is made of aluminum with the following properties: Elastic Modulus, E = 70 GPa and Shear Modulus, G = 25 GPa.
