Shown in the figure is a 12-gauge (0.1094-in) by ¾ -in latching spring that supports a load of F = 3 lbf. The inside radius of the bend is 1/8 in. Estimate the stresses at the inner and outer surfaces at the critical section.
Answer to relevant QuestionsThe cast-iron bell-crank lever depicted in the figure is acted upon by forces F1 of 250 lbf and F2 of 333 lbf. The section A-A at the central pivot has a curved inner surface with a radius of ri = 1 in. Estimate the stresses ...Two carbon steel balls, each 25 mm in diameter, are pressed together by a force F. In terms of the force F, find the maximum values of the principal stress, and the maximum shear stress, in MPa.A torsion-bar spring consists of a prismatic bar, usually of round cross section, that is twisted at one end and held fast at the other to form a stiff spring. An engineer needs a stiffer one than usual and so considers ...Using the results of Prob. 4–9, determine the end contraction of the uniformly loaded simply supported beam of appendix Table A–9–7. Assume the left support cannot deflect in the x direction, whereas the right support ...Illustrated in the figure is a 1 ½ -in-diameter steel countershaft that supports two pulleys. Pulley A delivers power to a machine causing a tension of 600 lbf in the tight side of the belt and 80 lbf in the loose side, as ...
