Question 2: (50 points) In the assembly shown below, the links AB and CD, which support the rigid member BC, are both made of aluminum (E = 75 GPa) and have each a cross-sectional area of 125 mm. If a load of P = 5 kN is applied at B, 1) Draw the Free Body Diagram. (10 POINTS) 2) Determine the normal stresses in both bars AB and CD. (14 POINTS) 3) Determine the downward deflections of points B and C on the rigid bar. (14 POINTS) 4) Draw the Deflection Diagram. (6 POINTS) 5) Deduce the downward deflection of point E on the member BC. (6 POINTS) A D P= 5 kN 0.36 m B ke 0.44 m 0.2 m
