Rigid bar ABC is supported by bronze rods (1) and (2) as shown below. A concentrated load of P = 35 kips is applied to the free end of rod (3). Each of the rods has an elastic modulus of E= 15000 ksi and an area of 0.2 in.². The rod lengths are L₁ = 11 ft, L₂ = 17 ft, and L3 = 9 ft. If a = 42 in. and b = 78 in., what is the downward deflection of the rigid bar at A?
