Hookes law - Study guides, Class notes & Summaries

Solid Mechanics 2 Marks Question with Answers UNIT -1 1. Define stress. When an external force acts on a body, it undergoes deformation. At the same time the body resists deformation. The magnitude of the resisting force is numerically equal to the applied force. This internal resisting force per unit area is called stress. Stress = Force/Area 2. Define strain When a body is subjected to an external force, there is some change of dimension in the body. Numerically the strain ...

This document will include: Forces Non contact forces + contact forces Mass + Weight + Moment Calculate moment, forces, mass and weight. Hooke's law Deformation

In this experiment you will study the stretching response of a rubber band (or a spring) and compare the observed behaviour with the predictions of Hooke’s Law.
