Friction is necessary evil. Explain.

Posted by Surinder Verma 7 years, 2 months ago

CBSE > Class 11 > Physics

3 answers

Ankit Singh ?????? 7 years, 2 months ago

Without friction we cannot set out the bodies in motion or stop the moving bodies. Thus friction is absolutely necessary for carrying day to day activities. On the other hand, it also wastes the time and energy, brings about wear and tear and slows down the motion. Thus, we can say that friction is a necessary evil.

3Thank You

Ayushi Ayushi 7 years, 2 months ago

In this platform we deal with conceptual explainations and therefore instead of a story on "Friction as a necessary evil" I provide you with below conceptual solutions. (i)- Friction is a necessary evil. (ii )- There are instances in daily life where friction is a necessity. (iii )- Without friction, we cannot hold objects in our hands, we cannot walk and we cannot light a matchstick, we would not be able to apply brakes in the moving vehicles etc (iv)- Friction has both advantages and disadvantages. (v)- And therefore, eventhough friction obstructs the intended motion, it is infact very important in daily life.

Explain stress and strain in detail with its different types.

Posted by Akanksha Kumari? 7 years, 2 months ago

CBSE > Class 11 > Physics

1 answers

Ankit Singh ?????? 7 years, 2 months ago

What are types of stress and strain? Stress: The internal resistance which the body offers to meet with the load is called stress . ie., tendency of a body to resist deformation which is caused by load acting on it. units are N/mm^2 or KN/mm^2 stress are classified into Simple or Direct stress Tension compression shear simple tension and simple compression occur when applied force (load) is linear with the axis of member and simple shear occurs when equal, parallel and opposite forces tend to cause a surface slide relative to adjacent surface. 2. Indirect stress: Bending Torsion In certain loading situations, stresses cause the member to bend resulting in deformation of material such stresses are called indirect stresses. 3.Combined stress: Any possible combination of direct and indirect stresses. Strain: The strain is deformation produced by stress Tensile strain: strain caused by tensional stress ie ratio of increase in length to actual length Compressive strain: strain caused due to compressive stress ie ratio of decrease in length to actual length Shear strain: in case of shearing load shear strain will be produced which is measured by an angle through which the body deforms Volumetric strain: it is ration between change in volume and original volume of the body
