- The vertical and horizontal poles at the traffic-light assembly are erected first. Determine the additional force and moment reactions at the base O caused by the addition of the three 117-lb traffic signals B, C, and D. Report your answers as a force magnitude and a moment magnitude. 22 A 29' 22" B. 117 lb 117 Ib 117 Ib Answers: O = Ilb Mo = i Ib-ftIn a game of freeze, a person freezes into a position shown below. As a percentage of total body mass, the head is 10%, the two arms are 10%, the trunk is 46%, and the two legs are 34%. The center of mass for each segment is given as an (x,y) coordinate, both units in cm: head = (130, 150),arms = (110, 75),trunk = (65, 95), andlegs = (0, 35). Assume the body mass for the individual is 75 kg and their total height is 160 cm. The length of the feet is roughly 10 cm. Determine the x and y-coordinates of the person's center of mass for this pose. Show all steps. Show the location of the center of mass on the diagram. Is this pose stable or unstable? Explain.In the figure, a man is trying to get his car out of mud on the shoulder of a road. He ties one end of a rope tightly around the front bumper and the other end tightly around a utility pole 29 m away. He then pushes sideways on the rope at its midpoint with a force of 550 N, displacing the center of the rope 0.28 m from its previous position, and the car barely moves. What is the magnitude of the force on the car from the rope? (The rope stretches somewhat.)
- Express each result of Parts 1-5 in the form of a Cartesian vector. Part 4 requires the specification of 2 cartesian vectors: a force and a moment vector.While Lost-a-Lot ponders his next move in the situation described and illustrated as shown, the enemy attacks! An incoming projectile breaks off the stone ledge so that the end of the drawbridge can be lowered past the wall where it usually rests. In addition, a fragment of the projectile bounces up and cuts the drawbridge cable! The hinge between the castle wall and the bridge is frictionless, and the bridge swings down freely until it is vertical and smacks into the vertical castle wall below the castle entrance. (a) How long does Lost-a-Lot stay in contact with the bridge while it swings downward? (b) Find the angular acceleration of the bridge just as it starts to move. (c) Find the angular speed of the bridge when it strikes the wall below the hinge. Find the force exerted by the hinge on the bridge (d) immediately after the cable breaks and (e) immediately before it strikes the castle wall.Calculate the combined moment of the three forces with respect to one of the axes. Use (a) the scalar method and (b) the vector method
