YOU ARE THE ONLY ONE ON THIS TOPIC ---EXCELLENT LECTURE

[mertgunes]

I don't understand how these videos don't have more views and likes, they're brilliant

[Manuel]

You are one of the best web content creators of the world, thank you very much.

[shanmukhansmmunagala]

Excellent explanation .Got clarity on the equations, really helpful thank you

[nishantduttmishra]

Thank you much for this. I was having trouble understanding how to incorporate the torque in the forcing function in the same way as we used generalized force Q.

[NeerajKumar-wvi]

How can we write the equation if it is written at CG for the same case

[NeerajKumar-wvi]

If we want to include both the translational and torsional damping along with the springs, then what would be the modifications?

[ThomasCynthiaMomo]

You have excellent handwriting and a fascinating accent. You should do professional voiceover work.

Hi, I really liked the video. I am wondering about the drag effect, there is not an horizontal force component in this type of movement?

[johnm]

For the derivation of kinetic energy (around the 2 minute mark), why is it heave rate minus pitch rate?

[brianwashingtonmusungwa]

Hello sir thank you for the whole work but

The lift acts on CP not CG ... So did we make an assumption that the CP and CG is at the same point ?

[ironpine]

For the kinetic energy term, why is the rotational KE just 0.5*J*alpha^2? Since the CG is in general plane motion (translation and rotation), don't we have to consider the components of its velocity (ie. like you did for the pendulum's mass in your pendulum on a cart video)?

[NeerajKumar-wvi]

I want to write mass decouple equations, .. please suggest the method

[mohemahmoude]

sir plz i need help on how to get Lagrange's Equations for 2DOF helicopter

[McTreestump]

Should there not be a potential energy term associated with the mass moving up or down?

Is it because the weight is supposed by the spring at the top?

[mechgyan]

Why you considered J about c.g. , not about the o??please sir

[ThomasCynthiaMomo]

Ah, I'm trying to understand flutter and all of the examples stop short of a rigorous explanation of the right hand side.
