Using the information in the footnote of Table 8–1, show that the tensile-stress area is
Answer to relevant QuestionsShow that for zero collar friction the efficiency of a square-thread screw is given by the equation. Plot a curve of the efficiency for lead angles up to 45◦ . Use f = 0.08.The C clamp shown in the figure for Prob. 8–7 uses a 5/8 in-6 Acme thread. The frictional coefficients are 0.15 for the threads and for the collar. The collar, which in this case is the anvil striker’s swivel joint, has ...A ¾ in-16 UNF series SAE grade 5 bolt has a ¾ -in ID tube 13 in long, clamped between washer faces of bolt and nut by turning the nut snug and adding one-third of a turn. The tube OD is the washer-face diameter dw = 1.5d = ...In the figure for Prob. 8–20, the bolts have a diameter of ½ in and the cover plate is steel, with D = ½ in. The cylinder is cast iron, with E = 5/8 in and a modulus of elasticity of 18 Mpsi. The ½ -in SAE washer to be ...A 1-in-diameter hot-rolled AISI 1144 steel rod is hot-formed into an eyebolt similar to that shown in the figure for Prob. 3–74, with an inner 2-in-diameter eye. The threads are 1 in-12 UNF and are die-cut. (a) For a ...
