Question
Q1: Rigid bar ABCD is loaded and supported as
shown in Figure, Bar (1) is made of bronze [E=100
GPa; a =
16.9 * 10-6 /0C) and has a cross sectional
area of 400 mm2. Bar (2) is made of aluminum [E=70
GPa; a
22.5 * 10-6 /0C) and has a cross sectional
area of 600 mm2. Bar (1) and (2) are initially
unstressed. If the temperature of bar (1) only has been
increased by 40 0C, determine
a) The stresses in bars (1) and (2).
b) The vertical deflection of point A.
