QUESTION 5: STATICS A light horizontal beam ABCDE is 8m long. It is supported at two points B and D. Point B is Im from the left end and D is 2m from the right end. The beam carries the following loads: A concentrated load of 20 N at A A concentrated load of 12 N/m over the first 5m from the left end A concentrated load of 30 N, 2m from the left end at C A concentrated load of 40 N at the right end E 5.1. Calculate the reaction at B and D 5.2. Calculate the bending moments at the principal points 5.3. Draw a fully labelled shearing force and bending moment diagram according to scale. ALL MAIN VALUES MUST BE INDICATED ON THE DIAGRAM [3] [6]
