yuan (yy3554) – HW #11 – Antoniewicz – (57380) 1 This print-out should have 20 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. 001(part1of2)5.0points A uniform horizontal beam of weight 468 N and length 4 . 14 m has two weights hanging from it. One weight of 368 N is located 1 . 23372 m from the left end; the other weight of 268 N is located 1 . 23372 m from the right end. What must be the magnitude of the one additional force on the beam that will produce equilibrium? Answer in units of N. 002(part2of2)5.0points At what distance from the left end must this force be applied for the beam to be in equilib- rium? Answer in units of m. 003(part1of4)3.0points Two weights are suspended as shown in the diagram. On the left, a weight of 110 N is suspended from its upper left by a string of tension T 1 angled at 51 with the horizontal. A string carrying tension T 2 is stretched be- tween them angled at 12 with the horizontal. On the right, the unknown weight W 2 is also suspended from its upper right by a string of tension T 3 angled at 47 with the horizontal. 110 N W 2 12 T 2 T 1 T 3 47 51 What is the tension T 1 ? The acceleration of gravity is 9 . 8 m / s 2 .
