A W530
66 structural steel [E = 200 GPa] wide flange shape is loaded and supported as shown in Figure P11.67. A uniformly distributed load of 70 kN/m is applied to the beam, causing the roller support at B to settle downward (i.e., displace downward) by 10 mm. Determine

(a) the reactions at supports A and B.

(b) the maximum bending stress in the beam.
