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. 270 mm 120 mm D. 120 mm F 90 E mm 120 mm 210 mm
