Two cables are used to suspend a bar that is approximated as rigid. A force is applied at the point shown. 3.33 Consider the case of A = A A = 0.1 in., E = E = E = 20 106 psi, L = 12 ft, L = 7 ft, L3 = 30 in., and L4 20 in. Take Fo 2000 lb. Determine the deflection of the bar (a) where cable 1 is attached, (b) where cable 2 is attached, and (c) where Fo is applied. 3.34 Consider the case of A = A = A and E A and E = E = E. Allow the cable lengths to differ by retaining the notation L and L. Find the ratio of L3/L4 at which the bar stays horizontal (the result will depend on variables L and L). = - 3.35 Consider the case of L = L = L and E E = E. Allow the cable areas to differ by retaining the notation A and A. Find the ratio of L3/L4 at which the stresses in the cables are equal (the result will depend on variables A and A). = E, A L -L3 L2 -L* Fo Probs. 3.33-35 E2, A2
