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

The rotation of a 11 kg motorcycle wheel is depicted in the figure. The wheel should be approximated to be an annulus of uniform density with inner radius R₁ = 27 cm and outer radius R₂ = 33cm.

Randomized Variables

ω = 132 rad/s
R₁ = 27 cm
R₂ = 33 cm
m = 11 kg

Calculate the rotational kinetic energy in the motorcycle wheel if its angular velocity is 132 rad/s in J.

Definition Definition Rate of change of angular displacement. Angular velocity indicates how fast an object is rotating. It is a vector quantity and has both magnitude and direction. The magnitude of angular velocity is represented by the length of the vector and the direction of angular velocity is represented by the right-hand thumb rule. It is generally represented by ω.
