2. The solid shaft ABCDE has a diameter of 30 mm and is simply supported at its ends. The pulleys at B and D are of diameter 200mm and pulley at C is 100mm in diameter. The pulleys are subjected to forces as shown in figure. The forces on pulley B are at an angle of 45 from the negative z-axis. The shaft sections have following lengths: AB = 100mm, BC 250mm, CD = 250mm, and DE 100mm. a. Determine the maximum bending and torsional stresses at the cross-section midway 25 N 100 N 500 N between points B and C. Locate the point(s) on 125 N 125 N 25 N AB = 100 BC=250 CD=250 DE=100 the cross-section where the stresses are maximum. b. Determine the maximum bending and torsional stresses anywhere along the beam. Locate the points(s) on the cross-section where the stresses are maximum. c. Determine the maximum principal stresses anywhere along the beam and locate the point(s) on cross section.
