Question

Bar DE is steel and has a cross sectional area of 0.25 in2 and a modulus of elasticity of 29,000 ksi. σsteel yield = 36 ksi.
Bar BC is brass and has a cross sectional area of 0.3 in2 and a modulus of elasticity of 15,000 ksi. σbrass yield = 30 ksi.
Bar ABDF can be considered rigid. Both the steel and brass bars are deformable. The weight of the bars can be assumed negligible in comparison to the forces they are supporting.
Find the axial stress in the steel and brass bars, and the deflection at point A
