1 CEE 240 / MIE 210 Statics NAME: [Final] Exam #3 Version A — 100 points (120 minutes) SHOW YOUR WORK USING THE COURSE PROBLEM SOLVING GUIDELINES! CALCULATORS ONLY – NO OTHER REFERENCES! 1. (25 points) An underwater instrument is modeled as shown in the figure. Determine the coordinates of the centroid of this composite volume. Note: the mass center of a sphere = 4 π r3/3. No FBD is required for this problem. 2 2. (25 points) Determine the range of weights W for which the 100-lb block is in equilibrium. All wheels and pulleys have negligible friction. 3 3. (25 points) Determine the force in each member of the loaded truss. 4 4. (25 points) The 480-lb V-8 engine is supported on an engine stand and rotated 90o from its upright position so that its center of gravity G is in the position shown. Determine the vertical reaction at each roller of the stand. Neglect the weight of the stand itself. 5 BONUS. (5 points) The cargo box of the food-delivery truck for aircraft servicing has a loaded mass m and is elevated by the application of a torque M on the lower end of the link which is hinged to the truck frame. The horizontal slots allow the linkage to unfold as the cargo box is elevated. Express M as a function of h.
