A uniform horizontal beam of length 8 m and weight 200 N is attached to a wall by a pin connection that allows the beam to rotate. Its far end is supported by a cable that makes an angle of 53degree with the horizontal. If a cable is strong enough to withstand T= 1200 N how heavy person can walk to the end of the beam? When that person was at the 0.75 distance from the wall, find: a. the...

A uniform beam (mass M = 64.0 kg and length L = 4.90 m) is supported by two triangular supports that are placed a distance D = 2.94 m apart, as shown below. The left-most support is at the very end of the beam. A person (mass m = 22.0 kg) starts walking at constant speed v along the beam, beginning from some point between the two supports. How close can the person get to the right-most end of the...

A drum of weight 200 N is supported by a beam of length s, weight W and a rope of length r. The mass per unit length of the beam is uniform. If the force exerted on the beam by the hinge is 200 N and acts at an angle of 25 above the horizontal then the tension in the cable of length r is TV zoo (a) 224 N (b) 79 N (c) 105 N (d) 338 N
