TASK 1 (P1) Figure 1 shows a simply supported beam carrying a point load and a uniformly distributed load. a) Calculate the support reactions R1 and R2. b) Draw the shear force diagram to scale. c) Calculate bending moments at 0 5m intervals along the beam and draw to scale the bending moment diagram. d) Find the values of the maximum shear force and maximum bending moment and show them clearly on the diagram. e) If the cross-section of the beam is rectangular of size 350mm depth and 250mm width what will be the maximum stress due to bending?

TASK 2 (P2) 2.1 An I-section steel beam of 4m length with end supports is required to carry a point load of 50kN in the middle of it. The maximum safe bending stress is to be limited to 85MPa. The Modulus of Elasticity of the steel (E) is 200GPa. a) Find the maximum bending moment that will be applied stating its position. b) Determine the Section Modulus for the beam and use it to
