1. The problem statement, all variables and given/known data
Classify each of the following items as a rigid body, a system of rigid bodies, or a non-rigid body: a fishing pole, a diving board, a mechanical spring, a bowling ball, a baseball bat, a system of gears, a slider block system, and a construction excavator's arm

2. Relevant equations

A body is considered rigid if it does not deform when a force is applied.

3. The attempt at a solution

Here's what I think:

Rigid Body:
bowling ball

System of Rigid Bodies:
System of gears, slider block system, construction excavator's arm

Non-Rigid Body:
spring, fishing pole, diving board, baseball bat

Please help me classify.
