Two polymer bars are connected to a rigid plate at B, as shown. Bar (1) has a cross-sectional area of 1.2 in.2 and an elastic modulus of 1820 ksi. Bar (2) has a cross-sectional area of 1.185 in.2 and an elastic modulus of 3590 ksi. Assume L1=21 in., L2=48 in., Q=7.6 kips, P=2.6 kips, and R=12.8 kips. Determine the horizontal deflection of end C relative to end A.
