When a hoisting cable is long, the weight of the cable itself contributes to the elongation. If a cable has a weight per unit length of w, a length of l , and a load P attached to the free end, show that the cable elongation is δ = Pl/AE + wl2/2AE
Answer to relevant QuestionsUse integration to verify the deflection equation given for the uniformly loaded cantilever beam of appendix Table A–9–3.The figure shows a cantilever consisting of steel angles size 4 X 4 X ½ in mounted back to back, Using superposition, find the deflection at B and the maximum stress in the beam.Illustrated is a rectangular steel bar with simple supports at the ends and loaded by a force F at the middle; the bar is to act as a spring. The ratio of the width to the thickness is to be about b = 16h, and the desired ...If the diameter of the beam for Prob. 4–26 is 1.375 in, determine the deflection of the beam at x = 8 in.Solve Prob. 4–13 using singularity functions. Use statics to determine the reactions.
