A torque of T_C
= 40 kip-in. acts on gear C of the assembly shown in Figure P6.84/85. Shafts (1) and (2) are solid 2.00-in.-diameter stainless steel shafts, and shaft (3) is a solid 1.75-in.-diameter stainless steel shaft. Assume that L = 8 in. and G = 12,500 ksi. Determine

(a) the maximum shear stress magnitude in shaft (1).

(b) the maximum shear stress magnitude in shaft segment (3).

(c) the rotation angle of gear E.

(d) the rotation angle of gear C.
