The system in the figure below is in equilibrium. A 45.0-kg beam that is hinged on the floor is also held at rest by the cable. A hanging mass of 225 kg is placed at the end of the beam. Calculate: 225 kg a) The tension in the cable; and b) The reaction forces exerted on the beam by the hinge. 30 45°
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.
The system in the figure below is in
equilibrium. A 45.0-kg beam that is hinged
on the floor is also held at rest by the cable.
A hanging mass of 225 kg is placed at the
end of the beam. Calculate:
a) The tension in the cable; and
b) The reaction forces exerted on the beam
by the hinge.
