A rectangular bar with cross section, h = 2 in. by b=0.75 in., is loaded by a fully reversed load P = 800 lb and a load F that varies from 400 lb to 700 lb at B, as shown in the figure on the right. In the figure, m = 8 in. and n = 12 in. a. Determine the mean and alternating axial stresses at a section to the left of point B. b. Determine the mean and alternating shear stresses at a section to the left of point B. c. Determine the mean and alternating normal stresses due to bending at a section thru B. m A rectangular bar with cross section, h = 2 in. by b=0.75 in., is loaded by a fully reversed load P = 800 lb and a load F that varies from 400 lb to 700 lb at B, as shown in the figure on the right.
