1. A 14-mm diameter brass rod AB is fitted with a plug at A. Rod is attached at B to rigid plate that is itself attached at C to the bottom of an aluminum cylinder with an outer diameter of 70 mm and wall thickness of 3 mm. The cylinder is then hung from a rigid support at D. The assembly is unstressed at 25°C with a vertical gap of 1 mm between the bottom of the plug and the bottom of the slot. When the temperature dropped to 4°C, (a) determine the force P required too close the cylinder y closing the gap), (b) corresponding strain in the rod and the cylinder and (c ) the deflection of the rigid plate. I mm AB (Brass) = 105 GPa D. a =20.9 x10-6/°C CD (Aluminum) E = 72 GPa a =23.6 x10-6/°C %3D 375 mm
