Study Notes
Rigid Body and Deformation
- A rigid body generally refers to an object that maintains its shape and size despite external forces applied to it.
Elasticity
- The property of a body that enables it to regain its original shape and size when an applied force is removed is called elasticity.
Changing Shape or Size
- An external force is required to change the shape or size of a body.
Helical Spring Deformation
- When a helical spring is gently pulled, its length increases.
Deformation Terminology
- The deformation caused by an applied force is termed strain.
