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.

A loaded cement mixer drivesonto an old drawbridge, where it stalls with its center of gravity threequartersof the way across the span. The truck driver radios for help,sets the handbrake, and waits. Meanwhile, a boat approaches, so thedrawbridge is raised by means of a cable attached to the end oppositethe hinge (Fig. ). The drawbridge is 40.0 m long and has a massof 18,000 kg; its center of gravity is at its midpoint. The cement mixer,with driver, has mass 30,000 kg. When the drawbridge has been raisedto an angle of 30° above the horizontal, the cable makes an angle of 70° with the surface of the bridge. (a) What is the tension T in the cablewhen the drawbridge is held in this position? (b) What are the horizontaland vertical components of the force the hinge exerts on the span?
