1.A picture of a man performing a pole vault, and the minimumradius of curvature of the pole is estimated by measurement to be4.5 m. If the pole is 40 mm in diameter and it is made of glass-reinforced plastic for which Eg=131 GPa, determinethe maximum bending stress in the pole.
2.An L2 steel strap having a thickness of 0.125 in. and a widthof 2 in. is bent into a circular arc of radius 600 in. Determine the maximum bending stress in the strap.
