Question 10 of 10 0/10 三 View Policies Show Attempt History Your answer is incorrect. Two polymer bars are connected to a rigid plate at B, as shown. Bar (1) has a cross-sectional area of 1.5 in.2 and an elastic modulus of 2400 ksi. Bar (2) has a cross-sectional area of 0.832 in.2 and an elastic modulus of 3110 ksi. Assume L1=16 in., L2-38 in., Q-8.2 kips, P=3.7 kips, and R=15.6 kips. Determine the horizontal deflection of end C relative to end A. R (1) (2) A B P L2 in.
