Concept explainers

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.

Question

A person on horseback is on a drawbridge which is at an angle e = 20.0° above the horizontal, as shown in the figure. The center of mass of the person-horse system is d = 1.00 m from the
end of the bridge. The bridge is l = 7.05 m long and has a mass of 1,960 kg. A cable is attached to the bridge 5.00 m from the hinge and to a point on the wall h = 12.0 m above the bridge.
The mass of person plus horse is 1,240 kg. Assume the bridge is uniform. Note that the drawing is not to scale and you may not assume that the cable is perpendicular to the bridge. (Due to
the nature of this problem, do not use rounded intermediate values in your calculations-including answers submitted in WebAssign.)
