2. A rigid, lightweight member ABC is supported by two uniaxially loaded rods as shown in the figure. ABC was initially horizontal before application of force P = 7 kN. Find the force in each rod, and calculate the downwards displacements of points A, B and C. The modulus of elasticity E = 200 GPa for both rods. $A_A = 85 \text{ mm}^2$ $A_C = 60 \text{ mm}^2$ 1.3 m 1.55 m A C B P = 7 kN 2 m 1 m
