It is about importance of constraints in virtual displacement, virtual work done and De' Alembert's principle of virtual work done. I would discuss numericals that could be asked.

(Hindi) De' Alembert's Principle-Physics: GATE

Overview (in Hindi)

A pre-requisite kind of lecture. If you know enough Newtonian Mechanics, you can skip this one. But I would suggest to go through this to become familiar with my notations and two beautiful problems.

Review of Newtonian Mechanics (in Hindi)

Learn to understand Constraints and Degree of Freedom of the particles in the system. Learn type of constraints and application of it in solving problems.

Constraints and DOFs (in Hindi)

Want to learn generalised coordinates and Configuration space? Well you will love this explanation.

Generalised Coordinates and Configuration Space (in Hindi)

Have an insight of virtual displacement and virtual work done. Feel the proof of De' Alembert's principle.

Virtual Workdone and De' Alembert's Principle (in Hindi)

Initial introduction of solving problems with help of De' Alembert's principle. Also explained why De' Alembert's principles are useful in spite of having Newton's Mechanics. In solving problem, if you find something unusual, then go and check next lecture as both are logically connected.

How and Why? (in Hindi)

Some more problems on De' Alembert's principle. Please combine this with previous lecture for clear understanding. Enjoy Physics!!!
