A rod is enclosed centrally in a tube and the assembly is tightened by rigid washer. If the assemble is subjected to a compressive load, then

Explanation:

• When a load is applied to the composite section from both ends in the same magnitude, the stresses developed in both the tube and the rod will be of the same nature.
•  If the compressive load is applied then compressive stresses will be developed in both tube and rod and if the tensile load is applied at both ends, then tensile stresses will be developed in both tube and rod.
• As the section is composite so their strain will also be the same in both rod and tube.
