ENGMEC3 – 2023 – ASSIGNMENT NO. 4 – SHEAR AND BENDING MOMENT IN BEAMS (40 pts)
A4.1 (15 pts) For the given beam with L = 4m, (a) Write the shear and moment equations per section using the
left as origin, (b) Draw the shear and moment diagrams specifying values at all change of loading positions and
at points of zero shear, (c) Identify the maximum absolute shear and maximum positive and negative moments
and their location.
