New Doubt in Rotation


I forget to put angle theta at point B.
Anyway ,could anyone solve this ?

The Vel & Accln of A are placed wrongly…
Specify the direction correctly…

Hint:Use constraint that vel & accln along the rod is same since rod is rigid

Are you sure ? I just copied the question from the book. And the concept of rigid body constraint is given after this problem. According to the , order given in the book it looks like it has be solved using uniform pure rolling (I dont know why?).
This is a solved example, so should i give the solution(I couldn’t understand it.) also?

there is some mistake in the question as the Va and Aa should be given at A and not B

Sorry that was a mistake

B is actually A.

Correct one

Another method for finding angular vel of rod would be by using ICR

The question isn’t fully solved yet
What about the acceleration?

differentiate the velocity obtained

italic a and italic w are angular velocity and angular acceleration

Why does the acceleration of A have a component at B pointing outward of the rod?
