Question

AL- Example 2-5: A solid circular steel cylinder S is encased in a hollow circular copper tube C. The cylinder and tube are compressed between two rigid plates of a testing machine by compressive forces P· The steel cylinder has cross- sectional area As, and modulus of elasticity Es 200-GPa the copper tube has area Ac and modulus of elasticity Ec-115-GPa, and both parts have length L For P-500-kN the shown table of values for As, Ac, and L determine a) the shortening d of the assembly, b) the compressive forces Ps in the steel cylinder and PcAnalysis of a statically in the copper tube, and b) the corresponding compressive stresses ss and sc. Fig. 2-17 Example 2-5 indeterminate structure
