This problem illustrates that the factor of safety for a machine element depends on the particular point selected for analysis. Here you are to compute factors of safety, based upon the distortion-energy theory, for stress elements at A and B of the member shown in the figure. This bar is made of AISI 1006 cold-drawn steel and is loaded by the forces F = 0.55 kN, P = 8.0 kN, and T = 30 N . m.
Answer to relevant QuestionsFind the current Ix in the 4-ohm resistor in the circuit shown. Determine the output voltage Vo of the summing op-amp circuit shown. The figure shows a shaft mounted in bearings at A and D and having pulleys at B and C. The forces shown acting on the pulley surfaces represent the belt tensions. The shaft is to be made of ASTM grade 25 cast iron using a ...A split-ring clamp-type shaft collar is shown in the figure. The collar is 2 in OD by 1 in ID by ½ in wide. The screw is designated as ¼ -28 UNF. The relation between the screw tightening torque T, the nominal screw ...For Eqs. (5–36) show that the principal stresses are given by
