6.13 A brass rod is a firm fit inside a steel tube 2 cm inside diameter and 4 cm outside diameter when the materials are at 15°C. If the rod and tube are now heated to a temperature of 150° C, calculate the maximum stresses in the brass and steel. Take the coeffi- cient of expansion for steel and brass as 10.8 × 10-6 and 18 x 10-6 per °C respectively. For steel E = 200 GPa and for brass E = 85 GPa. Poisson's ratio for both = 1/3. Neglect longitudinal frictional forces between the rod and the tube. %3D eleo

IV. Question 4 Two aluminium strips and steel strip are to be bonded together to form a composite member of width b and height h (Figure 5). The modulus of elasticity is 200 GPa for the steel and 75 GPa for the aluminium. Knowing that moment M is apply on the structure as shown in Figure 5, estimate the maximum stress in the aluminium and steel for the value of a from 0 to 20 mm using 2.5 mm increments.
