Rigid-Body Motion

 

Rigid-body motion

 

Rigid bodies experience what types of motion?

Check all that apply.

 

Rigid bodies may experience only translation (i.e. pure translation).
Rigid bodies may experience only rotation (i.e. pure rotation).
Rigid bodies may experience translation and rotation together (i.e. general motion).

 

 

 

 

 

 

Prerequisite knowledge

 

Rigid-body Newtonian mechanics requires understanding:

 

• center of mass (e.g. W is applied at G);
• moments (e.g. forces cause moments); and
• mass moment of inertia (e.g. resistance to angular acceleration).
