Unformatted text preview: the slope and deflection expressions using the singularity functions, (b) the reactions at both supports, (c) the bending moment at D. 4. (25 points) A torque is applied to gear A of a twoshaft system and is transmitted through gears at B and C to a fixed end at D. The shafts are made of steel (G = 80 GPa). Each shaft has a diameter d = 32 mm, and they are supported by frictionless bearings. If the torque applied to gear A is 400 Nm, and D is restrained, (a) determine the maximum shear stress in each shaft, and (b) determine the angle of rotation of the gear A relative to its noload position. 5. (25 points) A hollow steel shaft is 0.9 m long and has the cross section shown. The steel is assumed to be elastoplastic with σ Y = 180 MPa and G = 77 GPa. Determine the applied torque and the corresponding angle of twist (a) at the onset of yield, (b) when the plastic zone is 10 mm deep. Prof. Dr. M. Kemal Apalak Problem 1 Problem 2 Problem 3 Problem 4 Problem 5...
