SITUATION 8: The shaft shown is made of bronze and steel and is fixed at both ends. It is subjected to a concentrated torsional moment at the junction. 1. Find the ratio of the length of steel segment to the length of the bronze segment such that the allowable stress in each material is reached simultaneously. Bronze 75 mm dia. G = 35 GPa allow = 60 MPa T Steel 50 mm dia. G = 83 GPa allow T = 80 MPa 2. Determine the maximum torque (kN-m) that can be applied at the junction of the two segments if a = 2 m and b = 1.5 m. 3. If T = 4.5 kN-m, a = 2 m, and b = 1.5 m, calculate the rotation (in degrees) of the junction with respect to one end. ANSWERS: 1.186; 5.105 kN-m; 2.92°
