If you understand this and agree that you will neither give, nor use, nor receive unauthorized aid in this examination, please sign the Academic Integrity space on the examination booklet. Thank you. 1. Distributed Loads, Reactions. A beam of material of length L , width b and weight W is simply supported as shown in the figure. The beam is subjected to a linearly decreasing pressure distribution whose maximum value is given by p * decreasing to zero at L/ 2 . A particular beam of weight W = 7 N has dimensions L = 200 mm, b = 30 mm and is subjected to the pressure distribution for which p * = 0.01 N/mm 2 . L b p* L/2 A B A pressure-loaded beam. 20 Points (a) - 10 (b) - 10 (a) Replace the pressure load with an equivalent force R . Clearly indicate where R acts....
