Question

Problem 2: A fabric of woven polymer fibers is to held in tension while drying after a treatment in a chemical bath. Based on the schematic given below, find the force Fa required to maintain this tension, the maximum torsion experienced by the shaft and the reactions at A and B. Then draw the shear and bending moment diagrams for the shaft in both the x-y and y-z planes. Finally determine the maximum resultant bending moment and the location along the shaft where it occurs (treat point A as the origin). 0.1 m 005 m Rx Fo 0.5 m 0.05 m Ras RAs 0.075 m A zh Ras F900 N F 200 N 0.05 m Fo 0.05 md 0.075 m d z A F 200 N F=900 N
