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

Given the dimensions shown, determine the greatest axial load that can be applied to the rigid cap A without causing yielding of any one of the materials. mm 0.25 m SOLUTION 60 mm -10 mm
A bronze pipe (1) is to be connected to analuminum alloy pipe (2) at flange B. When put in place, however, a gap of A - 0.20 in. exists between the two pipes. Bronze pipe (1) has an elastic modulus of E, - 16,000 ksi, a cross-sectional area of Az - 2.75 in.?, and a length of L1- 44 ft. Aluminum alloy pipe (2) has an elastic modulus of E2 - 10,000 ksi, a cross-sectional area of A2 - 1.32 in. 2, and a length of L2 - 10.5 ft. If bolts are inserted in the flanges and tightened so that the gap at Bis closed, determine: (a) the normal stresses produced in each of the members.

The cutaway view shows a solid aluminum alloy [L2 = 730 mm; A2 = 693 mm?; E2 = 70 GPa] rod (2) within a closed-end bronze [L, = 741 mm; Az = 1125 mm²; E1 = 100 GPa] tube (1). Before the load Pis applied, there is a clearance of 3 mm between the rod flange at B and the tube closure at A. After load P = 200 kN is applied, rod (2) stretches enough so that flange B contacts the closed end of the tube at A. Calculate the internal force in bronze tube (1).

10 mm 20 mm The assembly above is comprised of a 10mm-diameter steel bolt, and a 20mm-diameter, 2mm-thick bronze sleeve. The bolt and sleeve are rigidly connected at each end by a washer. Assume the following properties: Epolt = 29000 ksi &bolt = 6.6-106 1°F Vbolt = 0.35 Member BC is made of bronze with the following properties: Esleeve = 15000 ksi Xsleeve =9.80-106 /°F Vsleeve = 0.35 If the assembly is heated up, which of the following statements best describes how the sleeve will be affected? The sleeve will try to expand longitudinally, but will be restricted by the bolt (because the bolt has a lower coefficient of thermal expansion). The sleeve will go into tension and the bolt will go into compression. O The sleeve will try to expand longitudinally, but will be restricted by the bolt (because the bolt has a lower coefficient of thermal expansion). Both members will go into tension.
