Extracted text: A compound shaft consisting of a 50mm diameter bronze segment and a 75mm diameter aluminum segment is subjected to two torques shown. Determine the maximum permissible value of T if the stress of bronze is limited to 60Mpa, the stress in aluminum is limited to 70mpa and the angle of twist of the free end is 10 deg. G for aluminum= 28GPA and G for bronze = 35 GPa. 27 37 Aluminum bronze
