Two people carry a heavy electric motor by placing it on a light board 2.10 m long. One person lifts at one end with a force of 410 N , and the other lifts the opposite end with a force of 670 N a) What is the weight of the motor? b) Where along the board is its center of gravity located? c) Suppose the board is not light but weighs 200 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? d) Where is its center of gravity located?
Rotational Equilibrium And Rotational Dynamics
In physics, the state of balance between the forces and the dynamics of motion is called the equilibrium state. The balance between various forces acting on a system in a rotational motion is called rotational equilibrium or rotational dynamics.
Equilibrium of Forces
The tension created on one body during push or pull is known as force.
