A compound shaft consists of a titanium alloy [G = 6,200 ksi] tube (1) and a solid stainless steel [G = 11,500 ksi] shaft (2).  Tube (1) has a length of L1 = 36 in., an outside diameter of D1 = 2.55 in., and a wall thickness of t1 = 0.160 in.  Shaft (2) has a length of L2 = 62 in. and a diameter of d2 = 1.25 in.  If an external torque of TB = 660 lb·ft acts at pulley B in the direction shown, calculate the torque TC required at pulley C so that the rotation angle of pulley C relative to A is zero.

Problem : Pressure vessel made of alloy steel with Yield Strength of 250 MPa, Pressure acting on Pressure Vessel = 10 Atmosphere. Longitudinal Stress (σL) = 200 MPa. Hooke's Law (E) = 150 MPa.
