The figure below shows a cutaway view of an assembly inwhich a solid bronze [G = 6,500 ksi] rod (1) is fitted inside of analuminum alloy [G = 4,000 ksi] tube (2). The tube is attached to afixed plate at C, and both the rod and the tube are welded to a rigidend plate at A. The rod diameter is d1 = 1.75 in. The outside diameterof the tube is D2 = 3.00 in., and its wall thickness is t2 = 0.125 in.Overall dimensions of the assembly are a = 40 in. and b = 8 in. Theallowable shear stresses for the bronze and aluminum materials are10,000 psi and 8,000 psi, respectively. Further, the rotation angle ofend B must be limited to a magnitude of 5°. On the basis of theseconstraints, what is the maximum torque TB that can be applied atend B?

2. The 40mm diameter steel rod AB shown in Figure 2 is resting on frictionless rollers between two steel plates. End A is just touching the left hand steel plate. Steel plate Steel plate А 1500mm Imm Figure 2 There is a gap of 1mm between the end B and the right hand side steel plate. The temperature of the rod increases by an amount AT and this increase in temperature causes the two ends of the rod to press against the steel plates. This action causes the right hand steel plate to move to the right by 0.5mm while the left hand plate does not move. The Young's modulus value for steel is 210,00ON/mm?. Taking any assumptions that you deem necessary calculate the increase in temperature AT required to cause the rod to buckle.
The figure shows a cutaway view of an assembly in which a solid bronze [G= 6,500 ksi] rod (1) is fitted inside of an aluminum alloy [G= 4,000 ksi] tube (2). The tube is attached to a fixed plate at C, and both the rod and the tube are welded to a rigid end plate at A. The rod diameter is d₁ = 1.05 in.

Q1. A bimetallic strip is used in temperature control systems as a safety component for automatic shutdown. You get two metal (Invar and yellow brass) with a length of 3.5 cm and thickness of 0.25 mm to construct the bimetallic strip. The system should work at the temperatures between -20 and 130 °C. Calculate the radius of curvature at the extremes of the design temperature range if two metals are bonded at 30•C.
