YOU MUST DRAW A FREE BODY DIAGRAM FOR EVERY ONE OF THESE PROBLEMS. Your FBD should include all the forces and/or moments that act on the body, and should include any known dimensions, slopes, angles, etc. Remember also that for every reaction that you find, your answer should include that reaction's magnitude, and an arrow indicating in which direction that reaction must act to maintain equilibrium of the body. 1. Determine the reactions at roller support A and pinned support B. 900 N/m 2. Bar ACB is supported by a pinned support at C, and by link AD (remember that we said a link behaves like a rope that can both push and pull (whereas a rope can only pull)). Links are one of the types of supports shown in Table 5-1. Determine the reactions at C and the force applied by link AD required to keep bar ACB in equilibrium. (You'll have to do a little thinking to figure out the slope of link AD. Just remember that slope is rise/run, so you'll have to figure out link AD's rise and run.) (Hint: you should draw a FBD of bar ACB.) Hint: Draw a FBD of the bar, the pulleys, and the rope that wraps around the pulleys all together as one object (they're all together in the bubble). Then, the only forces and moments that act from outside the bubble on the collection of things inside the bubble (and that, therefore, should be represented on the FBD) are the 42 N forces that are being applied by entities outside the bubble, and the reactions supplied by the fixed support at C. @ 42 N 3 m 11 in. -82mm 15 in. B 600 N/m 13 in. 3. The angled bar ABC has a fixed support at C. Pulleys A and B each have a diameter of 10 mm. Determine the reactions at the fixed support at C. 3 m 82 mm- 20? 1 68 lb 42 N C B 52 mm
