Question

AB: Area1 = 0.22 in2, E1 = 29x106 psi AC: Area2 = 0.15 in2, E1 = 10x106 psi 1. (10 pts) Find the Tension in AB 2. (10 pts) Find the Tension in AC 3. (8 pts) Find the Extension in AB 4. (8 pts) Find the Extension in AC 5. (14 pts) Find the Vertical Deflection at A P-4000Lb

Tension cords AB and AC are bot attached to their respective pins and are conjoined at point A with force applied vertically.

the E1 corresponding to Area2 should be E2 instead
