For the truss shown in Figure 3, members AC and BC have cross sectional area of 2 in.² while members AB and BD have cross sectional area of 4 in.2. E for all members is 11,000 ksi, and a for all members is 13 x 10-6 in./in./°F. • Compute the vertical deflection of joint B due to the applied 9 k load. Be sure to show both magnitude and direction. If member BC is heated by 150° F, what would be the resulting vertical deflection of joint A? ● 9 kips 8 ft. B Figure 3 8 ft. 12 ft.
