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 uniform plank is supported by two equal 120-N forces at X and Y, as
shown. The support at X is then moved to Z (half-way to the plank center).
The supporting forces at Y and Z are then:

FY = 40 N, FZ = 200 N
FY = 200 N, FZ = 40 N
FY = 80 N, FZ = 160 N
FY = 240 N, FZ = 120 N
FY = 160 N, FZ = 80 N

Check Your Understanding A 400.0-N sign hangs from the end of a uniform strut. The strut is 4.0 m long and weighs 600.0 N. The strut is supported by a hinge at the wall and by a cable whose other end is tied to the wall at a point 3.0 m above the left end of the strut. Find the tension in the supporting cable and the force of the hinge on the strut.

A uniform drawbridge must be held at a 38o angle above the horizontal to allow ships to pass underneath. The drawbridge weights 55000 N and is 15.0 m long.
