In Prob. 3-30, h →0 as x →0, which cannot occur. If the maximum shear stress τmax due to direct shear is to be constant in this region, show that the depth h at location x is given by
Answer to relevant QuestionsConsider a simply supported static beam of circular cross section of diameter d, so proportioned by varying the diameter such that the maximum stress σx at the surface due to bending is constant, when subjected to a ...Two 12 in long thin rectangular steel strips are placed together as shown. Using a maximum allowable shear stress of 12 000 psi, determine the maximum torque and angular twist, and the torsional spring rate. Compare these ...For the same cross-sectional area A = s2 = πd2/4, for a square cross-sectional area shaft and a circular cross-sectional area shaft, in torsion which has the higher maximum shear stress, and by what multiple is it ...Repeat Prob. 3–51 where the cylinder is subject to external pressure only. At what radii do the maximum stresses occur?A rotary lawn-mower blade rotates at 3000 rev/min. The steel blade has a uniform cross section 1/8 in thick by 1 ¼ in wide, and has a ½ -in-diameter hole in the center as shown in the figure. Estimate the nominal ...
