Question
The three-member frame has original dimensions as
shown in the figure. Elements F-D-B and A-B-E are
rigid. A downward vertical force P is applied at handle
F resulting in a deformation in element CD of S=0.135
mm. Determine a) the average normal ștress (Gavg) in bar
CD and b) the magnitude of the vertical force P. The
cross section area of bar CD is 250 mm2 and its modulus
of elasticity is E=200 GPa. Present the adequate FBD in
your solution, marks over the problem's image are not
considered a proper FBD. Solutions without FBD will
be graded as zero.
