![A load P will be supported by a structure consisting of a rigid bar ABCD, a polymer [E = 2,300 ksi; a = 2.9 x
10-6/°F] bar (1) and an aluminum alloy [E = 10,000 ksi; a = 12.5 x 10-6/°F] bar (2), as shown. Each bar has a
cross-sectional area of 2.00 in.2. The bars are unstressed when the structure is assembled at 30°F. After a
concentrated load of P = 61 kips is applied and the temperature is increased to 100°F, determine the
normal force in bar (1).
