Consider the beam loaded as shown below. The beam has a rectangular cross section with cross-section dimensions of b x h, where b is the dimension into the page Find: For this problem: a) Determine the location(s) for which pure bending exists on the cross section of the beam b) For the location(s) found in a) above, determine the maximum normal stress. For this problem, use the following parameters: L 5 m, w- 20 kN/m, b-0.1 m and h 0.3 m O B L12 L12
