Deformation of Solids in Physics

These flashcards cover fundamental concepts related to the deformation of solids, including tensile forces, tensile strength, Hooke's Law, Young's Modulus, strain, types of deformation, and elastic potential energy.

What do tensile forces do to a body?

They stretch the body.

What is tensile strength?

It is the amount of load or stress a material can handle until it stretches and breaks.

Define Hooke's Law.

It states that extension is proportional to the applied force up to the limit of proportionality.

What happens to a spring when a tensile force is applied?

It extends.

What is the spring constant?

It measures the stiffness of a spring and is defined as the force per unit extension.

What does the Young's Modulus measure?

It measures the ability of a material to withstand changes in length when under tension or compression.

What is strain in physics?

Strain is the extension per unit length and is dimensionless.

What type of deformation occurs when a material does not return to its original shape?

Plastic deformation.

Identify the elastic limit in a stress-strain graph.

It is the point beyond which a material cannot return to its original shape after the load is removed.

How is elastic potential energy defined?

It is the energy stored within a material when it is stretched or compressed.
