Homework About Torsion
The solid compound shaft, made of three different materials, carries the two torques shown. (a) Calculate the maximum shear stress in each material. (b) Find the angle of rotation of the free end of the shaft. The shear moduli are 28 GPa for aluminium, 83 GPa for steel and 35 GPa for bronze.

Sunk cost of a concrete mixer
A concrete mixer was bought for P30,000 six years ago. It will have a salvage value of P3,000 four years from now. It is sold now at P8,000. What is the sunk cost if the depreciation used is sinking fund method at 6%? Hint: sunk cost is the difference between the book value and the selling price.

Tension and stress of a chain lifting a beam
The 5m uniform steel beam has a mass of 600 kg and is to be lifted from the ring at B with the two chains, AB of length 3m., and CB of length 4m. a.)Determine the tension T in chain AB when the beam is clear of the platform. b.) stress if the cross-sectional area is limited to 500 mm2.

Applications Of Differential Equations
The radial stress p at distance r for the axis of the thick cylinder subjected to internal pressure is given by p + r (dp/dr) = A − p where A is a constant. If p = p0 at the inner wall r = r1 and is negligible (p = 0) at the outer wall r = r2 find an expression for p.
