One end of a uniform beam that weighs 3.50 ✕ 102 N is attached to a wall with a hinge pin. The other end is supported by a cable making the angles shown in the figure below. Find the tension in the cable. (Assume ?1 = 20° and ?2 = 37°.) Note: The answer is 244 N but I have no idea how to get there. Any help would be appreciated. Thanks.
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
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?

A beam with a length of 2 m and a mass of 10 kg supports a 50 kg box. The beam is connected to a wall by a hinge at its base and a horizontal wire. The wire is connected to the beam 1.5 m from the hinge and makes an angle θ of 35o to the beam. The goal is to find the tension in the wire and the horizontal and vertical components of the force exerted by the hinge on the board
