What is stress concentration?

• The lateral deformation produced in a body by an external force

• An increase in stress at discontinuities or flaws in a material

• The twisting of an elastic body about its longitudinal axis

• The bowing of an elastic body as an external force is applied transversely

What is shearing strain?

• The lateral deformation developed in a body in response to shearing stresses

• The force per unit area developed along a section of an elastic body

• An internal force tangential to the surface on which it acts

• The moment of a force system that causes rotation

What is the shear modulus?

• A coefficient of elasticity expressing the ratio between shearing stress and shearing strain

• The lateral deformation produced in a body by an external force

• An applied force producing shear in a body

• The bowing of an elastic body as an external force is applied transversely

What is bending?

• The lateral deformation produced in a body by an external force

• The bowing of an elastic body as an external force is applied transversely to its length

• The twisting of an elastic body about its longitudinal axis

• An increase in stress at discontinuities or flaws in a material

What is torque?

• The moment of a force system that causes or tends to cause rotation or torsion

• The twisting of an elastic body about its longitudinal axis

• An internal force tangential to the surface on which it acts

• The lateral deformation produced in a body by an external force
