Analyze the longitudinal schematic diagram of the metal beam shown, taking into account the support conditions, loads and dimensions presented. This diagram was idealized by taking important data from the real situation in the field. The cross section of the beam is rectangular, with a width of b = 80 mm and a height of h = 320 mm. First, find the Maximum Normal Stresses (Tension and Compression) and the Maximum Shear Stresses, showing where they occur (both longitudinally and transversely). Next, find the Normal Stress and Shear Stress at a point 200 mm above the base of the beam and 0.5 m from the left support. Compare your results to the Ultimate Stress or Yield Stress of a material and comment.
