Pure Rotation - Example 4.2-3

Derive the acceleration of any point on the rigid body shown undergoing pure rotation in terms of the

• radial distance (r)
• angular speed (ω)
• angular acceleration (α)

 



 

We will start the derivation with the n-t coordinate acceleration equation.

 



 

Which of the following equations represents the velocity of a point on a rigid body undergoing pure rotation?

 

v = r ω
v = r²ω
v = r ω²
