BENDING AND SHEAR STRESSES


CALCULATE MAXIMUM SHEAR STRESS

CALCULATE THE MAX BENDING STRESS IN BEAM

Problem 6.63 The steel shaft has a diameter of 1.5 in. It is supported on smooth journal bearings A and B which exert only vertical reactions on the shaft. 20 in.20 in._20 in.-20 in. 500 lb 300 lb 500 lb PartA Determine the absolute maximum bending stress in the shaft if it is subjected to the pulley loadings shown. Express your answer to three significant figures and include appropriate units. ?max = 1 Value Units Submit Request Answer
