- Isotopability
- Plasticity
Answer 1
B. The property of an object where it does not come back to its original size and share when the applied force is stopped is called
- Elasticity
- Removability
- Isotopability
- Plasticity
Answer 4
C. When an object is applied a deforming force, a ____ force _____ in magnitude is produced

- Restoring, equal
- Applied, unequal
- Applied, equal
Answer 2
D. If a cylinder is squeezed by applied forces, the restoring force / area is called
- Uncompressive stress
- Compressive stress
- Normal Stress
- Velocity Stress
Answer 2
E. Tangential stress is also known as
- Shearing Stress
- Normal Stress

- Normal Stress
Answer 1
F. If an object is immersed in the water, water applies force on it but the object grows internal restoring forces that are equal and opposite. The internal restoring forces per unit area are called:
- Hydraulic stress
- Solid Stress
- Object Stress
- Ice stress
Answer 1
G. Hooke’s law states that
- For small distortions, stress and strain have no relationship
- For small distortions, stress and strain are proportional to each other
- For large distortions, stress and strain have no relationship
- For large distortions, stress and strain are proportional to each other
Answer 2
H. Hooke’s Law is
- Empirical
- Theoretical
- Both Empirical and Theoretical
- Neither Empirical nor Theoretical
Answer 1
