A horizontal beam (ignore its mass) has a pivot at a point that is off-center, so that length l1 is different than length l2. In each case the unknown mass m is balanced by a known mass, M1 = 628 kg or M2 = 400 kg, so that the rod remains horizontal in rotational equilibrium. What is the value of m?
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.
