17 kg uniform store sign is held from a uniform horizontal beam as shown. There is a cable attached to the right edge of the beam and is secured to the wall, 250 cm above where the beam meets the wall. The sign is symmetrically suspended by two cords, the left cord being 80 cm from the wall, and the cord on the right being at the right edge of the beam, 200 cm from the wall. a. What is the tension in the left and right cords that hold the sign?   b. What is the tension in the cable?   c. What is the horizontal component of the force that the wall exerts on the beam?

Center of Gravity of a system

The centre of gravity is a property that is based on the geometry of a rigid body or any particle. It is described as an equilibrium point or a hypothetical location where the total weight of the body is concentrated.
