A torque is applied to gear A of a two-shaft system and is transmitted through the gears at B and C to the 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 radial bearings as shown in the figure. If the torque applied to gear A is 400 N-m and D is contained: (a) Determine the maximum shear stress in each shaft. (b) Determine the angle of rotation of gear A relative to its unloaded position.

The A-36 steel shaft has a diameter of 40 mm. (Figure 1) The gears are subjected to the torques T1 = 240 N·m, T2 = 75 N·m, and T3 = 315 N·m. Part A Determine the maximum shear stress in the segment AB. Express your answer to three significant figures and include appropriate units. Part B Determine the maximum shear stress in the segment BC. Express your answer to three significant figures and include appropriate units.

The bearings at A and B exert only x and z components of force on the steel shaft: Determine the shafts diameter to the nearest millimeter so that it can resist the loadings of the gears without exceeding an allowable shear stress of 82 MPa. Use the maximum-shear-stress theory of failure: 5kN 15mm 150 mm 350 mm R=1.5kN 250 mm a. None b. 43.9 mm c. 38.3 mm d. 43.5 mm e. 44.5 mm
