Two people carry a heavy electric motor by placing it on a light board 2.50 m long. One person lifts at one end with a force of 420 N , and the other lifts the opposite end with a force of 680 N.  weight of the motor: 1100N Suppose the board is not light but weighs 180 N , with its center of gravity at its center, and the two people each exert the same forces as before. What is the weight of the motor in this case? 920N Where is its center of gravity located?

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.
