For the beam and loading shown in Figure Q4: a) Calculate the reactions at the support. b)Draw the shear force and bending moment diagrams giving salient values. OIf the beam, made of steel, has a rectangular cross section with 275mm in width and uniform depth of 650 mm, calculate the maximum bending stress in the beam. The Young's modulus of the beam material is E = 200GPa. d)Find the minimum equivalent diameter of a circular steel section to carry thebending stress calculated in part c.
