Problem 1: A shop sign weighing 25 kg is supported by a uniform 15.82 kg beam, as shown in the figure above on the left. The beam is supported by a tension T provided by a cable that makes an angle of 35° with the beam. (a) What is the tension T in the cable? Answer: 708.1 N. (b) What is N, the horizontal component of the force the hinge (or pivot) exerts on the beam? Answer: 580.0 N. (c) What is N,, the vertical component of the force the hinge (or pivot) exerts on the beam? Answer: 6.1 N downwards.
