Question

of a brass core (diameter d, -8 mm) surrounded by a steel shell (inner diameter d2 8.75 mm, outer diameter d -10 mm), topped by a rigid cap. A load P compresses the core and shell, which have length L 120 mm. The moduli of elasticity of the brass and steel are Eb- 101 GPa and E 200 GPa, respectively. a) What load P will compress the assembly by 0.104 mm? b) If the compressive yield stress of the brass is 70 MPa and the compressive yield stress of the steel is 300 MPa, what is the maximum load P that may be allowed? Use a factor of safety of 1.33 with respect to yielding. Steel shell Brass core dz
