Wire 4) (20 points) A weight W is supported by attaching it to a vertical uniform metal pole by a thing cord passing over a pulley having negligible mass and friction. The cord is attached to the pole 40.0 cm below the top and pulls horizontal on it. The pole is pivoted at a hinge at its base, is 1.60 m tall, and weighs 50.0 N. A thin wire connects the top of the pole to a vertical wire. The...
1. A uniform horizontal bar of length L = 2.0 m and weight 144 N is pinned to a vertical wall and supported by a thin wire that makes an angle of 0 = 150 with the horizontal. A mass M, with a weight of 302 N, can be moved anywhere along the bar. The wire can withstand a maximum tension of 573 N. What is the maximum possible distance from the wall at which mass M can be placed...
In the figure, one end of a uniform beam of weight 460 N is hinged to a wall; the other end is supported by a wire that makes angles theta = 26 degree with both wall and beam. Find (a) the tension in the wire and the (b) horizontal and (c) vertical components of the force of the hinge on the beam.
A 3.0 m long horizontal pole (negligible weight), hinged at a wall, supports a 1500 N sign. The sign hangs 2.0 m from the hinge and, at the pole's other end, a cable pulls up and back at 53.1 degrees to the pole. (a) What is the Tension in the cable? (b) What is the horizontal part of the reaction force of the hinge on the pole?
