Torque, is the tendency of a force to rotate an object about an axis, fulcrum, or pivot. Just as a force is a push or a pull, a torque can be thought of as ... more

In engineering, deflection is the degree to which a structural element is displaced under a load. It may refer to an angle or a distance.
