Determine the moment M that should be applied to the beam in order to create a compressive stress at point D of sD = 10 MPa. Also, sketch the stress distribution acting over the cross section and calculate the maximum stress developed in the beam.

The beam is supported by a pin at point A and a roller at kN point B. A distributed load of W₁ = 8 - and an applied m force of F₁ = 12 kN are applied to the beam. The beam has an allowable bending stress of allow = 6 MPa. Neglect the weight and thickness of the beam. Take the origin for all functions to be at A., i.e. start at the left and go right.
