Elastic Materials

This type of elastic modulus measures the resistance of solids or liquids to changes in their volume.

• Young's Modulus

• Shear Modulus

• None of these

The elastic modulus is a proportionality constant that depends on the material being deformed and on the nature of the deformation.

• true

• false

____________Is a quantity that is that is proportional to the force causing deformation; more specifically it i the external force acting on an object per cross sectional area.

• stress

• strain

• modulus

• Length

The measure of the degree of deformation is

• stress

• strain

• radius

• none of these

The ____________stress is the ratio of the magnitude of the external force to the cross sectional area A where the cross section is perpendicular to the force vector.

• tensile stress

• shear stress

• volume stress

• None of these

The ____________stress is the ratio of the tangential force to the area A of the face being sheared.

• tensile stress

• shear stress

• volume stress

• None of these

The ____________stress is the ratio of the magnitude of the total force F exerted on a surface to the area A of the surface.

• tensile stress

• shear stress

• volume stress

• None of these

The reciprocal of bulk modulus is compressibility.
