What do you call the force which determines whether the body will be in equilibrium or have a varying state of motion?

• Equilibrium

Identify the principle used in equations related to the deformation of axially loaded materials: That the stress is proportional to the strain within the Elastic Region.

• Hooke‘s Law

• Young‘s Modulus

• Poisson‘s Ratio

• St. Venant‘s Principle

Identify the principle used in equations related to the deformation of axially loaded materials: That in the deformatio of axially loaded members, the ratio of the lateral to the longitudinal strain is constant.

• Hooke‘s Law

• Young‘s Modulus

• Poisson‘s Ratio

• St. Venant‘s Principle

Identify the principle used in eqautions related to the deformation of axially loaded materials: That within the elastic range, it is the constant of proportionality that defines the linear relationship between stress and strain.
