Answer 1

Answer:

Explanation:

A mild steel rod of 20 mm diameter and 300 mm long is enclosed centrally inside a hollow copper tube of external diameter 30 mm and internal diameter of 25 mm. The ends of the tube and the rods are brazed together and the composite bar is subjected to an axial pull of 40 kN. if E for steel and copper is 200 GN/m and 100 GN/m respectively. Find the stresses developed in the rod and the tube. Also find the extension of the rod
