A 0.19 kg horizontal beam has length L-0.8 m. It is supported by a fulcrum at d=0.50 m from the left end. A 0.25 kg mass ml is suspended at xl=0.25 m from the bar's left end. Another mass mr is suspended at xr30.80 m from the bar's left end. The system is in equilibrium. How heavy in kg is the mass mr on the right side? Hint: the bar's gravity has a torque if it is not supported by the fulcrum at exactly half way.

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.
