Question

2013 Michael Swanbom 08 O Cross Section Dimensions 106 cm 25 cm 32 mm 33 mm Problem Statement A cantilever beam has a cross-section shaped as a sector of a circle. It is supported at A and loaded with a concentrated load of F 870 N and a concentrated moment of M = 361 N*m. The dimensions of the beam are given in the table above. Find the normal stresses at points D, E, and G in the cross-section, at the locations along the beam's length where it experiences its maximum positive and maximum negative bending moments Reactions: RA870 N MA-778.7 N'm Flexural Normal Stresses: (Denote tensile stresses with positive values, compressive stresses with negative values) Stress at Point D Stress at Point E Stress at Point G Location along length Location of Max Positive Bending Moment Location of Max Negative Bending Moment be sure to include units with your answers
