A beam with 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. A. In order to find the tension in the string, which point should we select to write ?(a)Top left end of the beam(b)Point where wire is connected to the beam.(c)Middle of the beam (where mg acts).Bottom right end of the beam(d) Use the point you identified in C to calculate the tension in the string.
An 66 kg man is climbing up a 7.0 m ladder that is resting against a smooth, frictionless wall. The ladder has a mass of 10 kg and it makes an angle of p=58° with the ground.
