A rigid block of weight W is supported symmetrically by two steel rods and one aluminum rod as shown in figure on next page. The two steel rods are further supported by link ABC and DEF made of hollow circular sections having external and internal diameters of 15 mm and 10 mm respectively. The aluminum rod is supported by steel plate GH having rectangular section (5 mm x 10 mm). The connection between aluminum rod and steel plate is through a pin of 5 mm diameter in double shear. W is equal to 5000 newtons. The temperature of two steel rods and one aluminum is increased by 20 °C.
