A steel strip of cross-section 5 cm by 1.25 cm is bolted to two copper strips, each of
cross-section 5 cm by 0.9375 cm, there being two bolts on the line of pull. Show that,
neglecting friction and the deformation of the bolts, a pull applied to the joint will be
shared by the bolts in the ratio 3 to 4. Assume that E for steel is twice E for copper.
