1. A small 42.0 N sign is suspended from the end of a hinged rod, which is 2.40 m long and uniform shape as shown in the diagram below and to the right. Mat tension force exists in the rope holding up both the rod and the sign? The rope makes an angle of 60" with the F 36.0 N rod. \"1' in N 42.0 N HJ. I'I'I'I . 1! In 0 2. A beam of negligible mass is attached to a wall by means of a hinge. Attached to T Z ? the centre of the beam is a 4-30. N weight. A rope also helps to support this beam as shown in the diagram. a} What is the tension in the rope? b} What are the vertical and horizontal forces that the wall exerts on the beam? 3. Find the tension in the rope supporting the 200. N hinged uniform beam as shown in the diagram. |\\
