Two solid steel shafts (G 5 77.2 GPa) are connected to a coupling disk B and to fixed supports at A and C.
For the loading shown, determine (a) the reaction at each support, (b) the maximum shearing stress in
shaft AB, (c) the maximum shearing stress in shaft BC.
Problem. Two solid shafts made out of steel (G = 77 GPa) are connected by the gears shown.
Find the angle through which end A rotates when TA = 75 N·m.
