## FAQs on Short Tricks for Revision: Mechanical Properties of Solids Video Lecture - Physics Class 11 - NEET

 1. What are the mechanical properties of solids?
Ans. The mechanical properties of solids refer to the physical characteristics that describe how a solid material responds to external forces or loads. These properties include elasticity, plasticity, strength, hardness, toughness, and ductility.
 2. How is elasticity defined in the context of mechanical properties of solids?
Ans. Elasticity is the ability of a solid material to deform under the influence of an external force and return to its original shape and size once the force is removed. It is characterized by the material's ability to store and release energy.
 3. What is the difference between strength and hardness in the context of mechanical properties of solids?
Ans. Strength refers to the ability of a material to withstand an applied force without undergoing permanent deformation or failure. On the other hand, hardness is a measure of a material's resistance to indentation or scratching. While both properties are related to a material's ability to resist deformation, strength is more concerned with overall resistance to failure, while hardness focuses on localized resistance.
 4. What is the significance of toughness in mechanical properties of solids?
Ans. Toughness is a measure of a material's ability to absorb energy and deform plastically before fracturing. It indicates the material's ability to withstand sudden impacts or shock-loading without breaking. Higher toughness values are desirable for applications where the material is subjected to high stress or impact forces.
 5. How does ductility influence the mechanical properties of solids?
Ans. Ductility is the ability of a material to undergo plastic deformation under tensile stress without fracturing. Materials with high ductility can be stretched into thin wires or drawn into thin sheets. Ductile materials can absorb more energy before failure and are desired in applications where deformation without fracture is necessary, such as in metal forming processes.
