Physics: Deformation and Related Concepts

Front

Deformation

Back

Change in the shape or size of an object.

Front

Tensile Deformation

Back

An object is stretched.

Front

Compressive Deformation

Back

The object is squeezed or compressed.

Front

Hooke's Law

Back

Provided the elastic limit is not exceeded, the extension of a body is proportional to the applied load. F = kx

Front

Extension

Back

The extended length minus the natural or original length.

Front

Stress

Back

Ratio of force to cross-sectional area.

Front

Tensile Strain

Back

The ratio of extension to the original length.

Front

Young's Modulus

Back

The ratio of stress to strain.

Front

Limit of Proportionality

Back

In this region, the extension of the spring is proportional to the load.
