4. A horizontal beam weighing 300 N is attached to a wall. It is supported by a cable which makes an angle of 30° with the horizontal beam. If a 60.0 kg block is placed 3.00 m from the wall, determine (a) the tension in the cable and (b) the horizontal and vertical components of the force exerted by the beam at point O. 60.0 kg 30.0

4. A horizontal beam weighing 300 N is attached to a wall. It is supported by a cable which makes an angle of 30° with the horizontal beam. If a 60.0 kg block is placed 3.00 m from the wall, determine (a) the tension in the cable and (b) the horizontal and vertical components of the force exerted by the beam at point O. 60.0 kg 30.0° -10.0 m - 5. In a construction site, two vertical cables are supporting a 3.00m steel beam weighing 1500N. Suppose cable A can support a maximum weight of 2000N while cable B can support a maximum weight of 3000N. A construction worker would like to place an object on the horizontal beam, what is the maximum mass that he can put without breaking the cables? where should the object be located?
