Unformatted text preview: 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 (part 1 of 2) 5.0 points 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 (part 2 of 2) 5.0 points 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 (part 1 of 4) 3.0 points 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 4 7 5 1 What is the tension T 1 ? The acceleration of gravity is 9 . 8 m / s 2 ....
