Simplify Eqs. (3–70), (3–71), and (3–72) by setting z = 0 and finding σx /pmax , σy/pmax , σz/pmax , and τ2/3/pmax and, for cast iron, check the ordinate intercepts of the four loci in Fig. 3–37.
Answer to relevant QuestionsA 6-in-diameter cast-iron wheel, 2 in wide, rolls on a flat steel surface carrying an 800-lbf load. (a) Find the Hertzian stresses σx, σy, σz, and τ2/3. (b) What happens to the stresses at a point A ...A bar in tension has a circular cross section and includes a conical portion of length l , as Shown, the task is to find the spring rate of the entire bar. Equation (4–4) is useful for the outer portions of diameters d1 ...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 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 ...Shown in the figure is a uniform-diameter shaft with bearing shoulders at the ends; the shaft is subjected to a concentrated moment M = 1200 lbf ?in. The shaft is of carbon steel and has a = 5 in and l = 9 in. The slope at ...
