Rigid, Non-Rigid and System of Rigid Bodies?

In summary, a fishing pole, diving board, mechanical spring, and construction excavator's arm are considered non-rigid bodies as they deform when a force is applied. A bowling ball is a rigid body as it does not deform. A system of gears and a slider block system are classified as systems of rigid bodies, while a baseball bat is debatable, but could also be considered a rigid body.

Rigid, Non-Rigid and System of Rigid Bodies?

Homework Statement


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

Homework Equations



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

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.

I would call the baseball bat rigid. The rest look OK.
 

What is the difference between rigid and non-rigid bodies?

Rigid bodies are objects that do not change shape or size when subjected to external forces, while non-rigid bodies can change their shape or size under the influence of external forces.

What is a system of rigid bodies?

A system of rigid bodies is a collection of rigid bodies that are connected to each other by joints or links and move together as a single unit.

What are some examples of rigid and non-rigid bodies?

Examples of rigid bodies include a metal bar, a brick, and a baseball bat. Examples of non-rigid bodies include a rubber band, a balloon, and a sponge.

What are the applications of rigid and non-rigid bodies in science and engineering?

Rigid bodies are commonly used in mechanical engineering for designing structures and machines, while non-rigid bodies are often used in material science for studying the properties and behavior of different materials.

What are the principles governing the motion of rigid bodies?

The motion of rigid bodies is governed by principles such as Newton's laws of motion and the conservation of energy and momentum. These principles describe how forces and energy affect the motion of rigid bodies.
