A 250 mm long rod with a 15×30 mm cross section consists of a brass layer joined by welding in the middle of 2 aluminum layers. If the magnitude of the axial and centripetal P force is 45 kN and Ea=70 GPa and Ep - 105 GPa, find the stresses in th
e aluminum and brass layer.
The assembly is composed of a steel shell and an aluminum
core that has been welded to a rigid plate. The gap between the
plate and the aluminum is initially 1- mm. If the assembly's
temperature is reduced by 180°C, determine (a) the final axial
stresses in each material and (b) the deflection of the rigid bar.
To support your response, draw a deformation diagram with
appropriate labels.
