For the following Problem:

1. For steel members unless otherwise noted, use a modulus of elasticity of 30,000,000 psi (207 × 103 MPa). For other materials, refer to the appropriate appendix table.

2. Unless otherwise noted, the given loads are superimposed loads; neglect the beam weight; neglect shear and moment considerations.

3. Unless otherwise noted, use any appropriate method to calculate deflection.

A 500-mm-long steel bar having a cross section of 1 mm by 20 mm is bent to a circular arc that subtends an angle of 60° as shown. Calculate the maximum bending stress.
