Question
Q1: Rigid bar ABCD is loaded and supported as shown in figure below.
Bars (1) and (2) are unstressed before the load P is applied. Bar (1)
is made of bronze [E = 100 GPa] and has a cross-sectional area of
520 mm2. Bar (2) is made of aluminum [E = 70 GPa] and has a
cross-sectional area of 960 mm2. After the load P is applied, the
force in bar (2) is found to be 25 kN (in tension). Determine:
(1) the stresses in bars (1) and (2).
(2) the vertical deflection of point A.
(3) the load P.
