FAQs on NCERT Solutions Class 11 Physics Chapter 8 Mechanical Properties of Solids
1. What are Some Mechanical Properties of Solids?
Mechanical Properties of Solids Class 11 NCERT PDF go into the depths of the topic. It also describes the various mechanical properties of solids, some of which are as follows:
Brittleness: Brittleness is the property of solids due to which they break into smaller pieces when enough force is applied.
Compressive Strength: Due to their compressive strength, solids resist being pushed together.
Ductility: It is the property of solids that results in their deformation under tensile strength.
Elasticity: An elastic substance is capable of resisting distortions or deformations under an applied force. These materials return to their original shape when the force is removed.
Other than that, solids also show plasticity, which is the ability to undergo permanent deformation when a force is applied.
2. What is Elastic Moduli?
Most solids resist elastic deformation when stress is applied. Elastic modulus is the quantity that measures this resistance. It is an important inclusion of Class 11 Physics Chapter 9.
3. What is Hooke’s Law?
Hooke’s law states that the size of deformation of an object is directly proportional to the force of deformation.
4. What is an intermolecular force?
As discussed in the chapter, the force of attraction or repulsion acting between the particles (atoms, molecules and ions) neighbouring each other, is referred to as the intermolecular force of attraction or repulsion. Intermolecular forces are considered weaker in comparison to the intramolecular (covalent and ionic bonds) force acting between the atoms and molecules. Examples of intermolecular force are the London dispersion force, ion-dipole interaction etc.
5. What are the practical applications of the Mechanical Properties of Solids Class 11?
Solid mechanics has a plethora of real-life applications. It is one of the most fundamental applied engineering sciences which plays a crucial role in explaining a lot of physical phenomena around us and in explaining human anatomy. It is also used extensively in surgical implants and the design of dental prostheses. The principles and properties of solid mechanics have also been used in the Euler–Bernoulli beam equation.
