P6.16 A compound shaft (Figure P6.16) 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 L₁ = 40 in., an outside diameter D₁ = 1.75 in., and a wall thickness t₁ = 0.125 in. Shaft (2) has a
length 42 = 50 in. and a diameter d₂ = 1.25 in. If an external torque TB = 580 lb ft acts at pulley B in the direction shown, calculate the torque Tcrequired at pulley C so that the rotation angle of pulley Crelative to A is zero.
