• The resistance of a material to deformation

• The amount of energy stored in a material

Strain is defined as:

• The force applied per unit area

• The maximum stress a material can withstand without breaking

• The energy required to break a material

Ultimate tensile stress refers to:

• The maximum stress a material can withstand without breaking

• The maximum stress a material can withstand at any point

• The point beyond which the stress-strain curve becomes non-linear

• The point beyond which the material fractures or breaks

• The maximum strain a material can undergo without permanent deformation

Deformation refers to:

• The force applied per unit area

• The change in shape or size of a material due to stress

• The resistance of a material to deformation

• The amount of energy stored in a material

Compressionrefersto:
