a 50.0 kg uniform square sign, of edge length L=2.00m, is hung from a horizontal rod of length dh = 3.00 m and negligible mass. A cable is attached to the end of the rod and to a point on the wall at distance dv = 4.00 m above the point where the rod is hinged to the wall. (a) What is the tension in the cable? What are the (b) magnitude and (c) direction (left or right) of the horizontal component of the force on the rod from the wall, and the (d) magnitude and (e) direction (up or down) of the vertical component of this force?
A man stands a distance d = 0.275 m from the left end of a platform as shown in the figure. The platform is supported by three cables. Find the tension in each cable (in N). Assume the platform is uniform, with length L = 2.00 m and mass 35.0 kg, and the weight of the man is 690 N. (Due to the nature of this problem, do not use rounded intermediate values in your calculations—including answers submitted in WebAssign.) (b). What If? The man now begins to walk to the right. If each of the cables can support a maximum tension of 800 N, which cable fails first? At what location does this occur (measured in m from the left end of the platform)?
Suppose the length L of a uniform bar is 3.20 m and its mass M =15.2 Kg. Also, m1 = 11.4 kg, m2 = 24.8 kg, m3 = 17.3 kg, and the angle θ = 32 ̊. The distance from wall to the center of mass of m1 is 1.02 m, m2 is 2.10 m, and m3 is 3.20 m. What is the tension in the wire?
A fisherman has caught a fish on his pole, and to keep the pole steady he has to apply an upward force of F2 = 265 N at an angle of 58° with respect to the pole (see figure). The length of his pole is 3.2 m, and he is holding it a distance 0.65 m from the end, where he is applying a downward force F1. Part (a) With how much force, F1, in newtons, does he have to push straight downward on the end of his pole to keep the pole from moving? You may assume the pole is massless. Part (b) What is the mass of the fish on the end of the pole, in kilograms?

A uniform horizontal beam 5.00 m long and weighting 3.03 102 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 53.0° with the horizontal (Figure (a)). If a person weighing 6.05 102 N stands 1.60 m from the wall, find the magnitude of the tension in the cable and the force exerted by the wall on the beam. T = N Rx = N Ry = N Even if we selected some other axis for the torque equation, the solution would be the same. For example, if the axis were to pass through the center of gravity of the beam, the torque equation would involve both T and Ry. Together with Equations (1) and (2), however, the unknowns could still be found—a good exercise. In this example, notice the steps of the Problem-Solving Strategy could be carried out in the explicit recommended order.QUESTION What happens to the tension in the cable if the man in Figure (a) moves farther away from the wall? The tension would…
