Q. 2. What are the mechanical properties of material? Ans. The mechanical properties of materials define the behavior of materials under the action of external forces, called loads. They are a measure of the strength and lasting characteristics of a material. Q. 3. Define the term 'strength' of a material. Ans. The strength of a material is its capacity to withstand the action of external loads. The stronger the material the greater the load it can withstand. Q. 4. What is elasticity? Ans.
