The beam AB is loaded with a uniformly distributed load as well as a point load at its midpoint, as shown. The beam has an I-section with dimensions shown. Use the following values in your working out: L = 10 mm b = 320 mm h = 460 mm t = 10 mm F = 8 KN w = 4 kN/m W A L/2 F L B b a) Draw the Free Body, Shear Force and Bending Moment diagrams on your response sheet using the axes provided. Label any important points such as maxima and minima on your diagrams. (1.5 marks) b) What is the maximum bending stress experienced in the beam? What is its nature (tensile or compressive)? (1 mark) c) What would be the effect of rotating the beam by 90 degrees about its longitudinal axis? (ie. "b" would become the vertical distance as seen in the loading diagram) (0.5 marks) The beam AB is loaded with a uniformly distributed load as well as a point load at its midpoint, as shown.
