3.35) The motor A delivers 3000 hp to the shaft at 1500 rev/min, of which 1000 hp is removed by gear B and 2000 hp is removed by gear C . Determine (a) the maximum shear stress in the shaft; and (b) the angle of twist of end D relative to end A . Use G=12x10^6 psi for steel, and assume that friction at bearing D is negligible.

answer is a) A B -Tmax=10,030psi

BC -Tmax=9980psi

b)0.05289rad=3.03 degrees
