Question 8 (9 marks) A 1 220 N uniform beam is attached to a vertical wall at one end and is supported by a cable at the other end. The beam is at an angle of 30 above the horizontal and the cable hangs at an angle of 50 above the horizontal, as shown in the gure. A 1 960 N crate hangs ow the far end of the beam. a) Draw a force diagram showing all the forces acting on the beam. h) Find the magnitude of the tension in the cable. c) Find the magnitude of the horizontal and vertical components of the force that the wall exerts on the left end of the beam. a) Force diagram: b) Tension: c) Horizontal: Vertical
