Two 1otors A and B are attached to the ends of a sha m n long. The mass of the rotor A is 400Kg and its radius of gyration is 400mm. The corresponding values of rotor B are S0OK und S00mm respectively. The shaft is of 80mm diameter. Modulus of rigidity of the shaft material is 0.10'MN/m. Find the- (a) Frequencies of torsional vibrations (b) Position of the node und mode shaper. Xx
Free vibration (mg=k×del) but torsional vibration why torsional stiffness takes as negative symbol its indicate only direction then why you takes for magnitude substution

Thank you sir... Love from Sri Lanka 😍😚
Oh. I found it. It's not included in the playlist
Please add
sir aap acche aadmi hain!!

Nice sir 👍❤️
Its been difficult to find out the playlist only for vibration ..can you share the link of vibration only
sir excellent lecture --pls name book
sir why dont we consider the MOI of rod . bcoz both disc as well as rod will have tendency to restore applied torque ? please explain
Because of negligible rod mass
thanks
Sir Vibration absorbers
Conceptually this is a bit difficult to comprehend. Is the disc fixed to the wall? If so then we have statics problem? How can there be acceleration?
Shaft fixed to the wall. Shaft is elastic and rotate
Yes sir it difficult
