![Problem 5
Rigid bar ABCD shown in the figure is supported by a
smooth pin at D and by vertical aluminum alloy [E = 10,000
ksi] bars attached at joints A and C. Bar (2) was intended to
have a length of 60 in.; however, its actual length after
fabrication was found to be L2= 59.88 in. To connect it to
the pin at C on the rigid bar, bar (2) will need to be manually
stretched by A = 0.12 in. After bar (2) has been stretched
and connected to the pin at C. Use the following additional
properties and dimensions: A1 = A2 = 0.75 in², Determine:
(a) the normal stresses in bars (1) and (2).
(b) the deflection at A of the rigid bar.
