The compound shaft, consisting of steel and aluminumsegments, carries the two torques shown in the figure. Determine themaximum permissible value of T subject to the following designconditions: τst ≤ 83 MPa, τal ≤ 55 MPa, and θ ≤ 6⁰ (θ is the angle ofrotation of the free end). Use G =83 GPa for steel and G = 28 GPa foraluminum.
The solid compound shaft, made of threedifferent materials, carries the two torques shown. Theshear moduli are 28 GPa for aluminum, 83 GPa for steel,and 35 GPa for bronze.1. Calculate the maximum shear stress (MPa) in eachmaterial.2. Find the angle of rotation (degrees) of the free endof the shaft.

The exhaust (product) leaves the engine at 800 K, and the heat lost to the coolant is 3.4×105 kJ/kmol. What is the engine's output power? Assume both air and fuel (methane) inlet to the engine at 298 K. Take for methane, the molecular weight is M = 16 kg/kmol, and the heat of combustion is 50.01 MJ/kg.
