ENGINEER 2P04 - ENGINEERING MECHANICS "A" PRACTICE PROBLEM SET: 7 This problem set contains 10 problems. Please solve them prior to the tutorial time. Only the problems indicated with * will be discussed during the tutorial time. Solutions to this problem set will be posted at the Course Website. 1. The rectangular cross-sectional links BC and DE are both made of steel (E=200GPa), and are 12mm wide and 6mm thick. If a 10kN force P is applied to the rigid member AF shown in Figure: 1, determine (a) the force in link BC, and the force in link DE (b) Determine the reactions at support F. (c) Determine the deflection of Point A. 2.* The steel rods BE and CD each have a 16-mm diameter (Take E st =200GPa.). The ends of the rod are single threaded with a pitch of 2.5mm. Knowing that after being snugly fitted, the nut at C is tightened one full turn, determine (a) the stress in rod CD, (b) the stress in rod BE, and (c) the deflection of point C of...
