Could someone please explain me why the velocity of point P and P' aren't the same? Appearently it is because the angular velocity of point A and B aren't the same.
We are only given that the angular velocity of A is 10rad/s clockwise.
Why? I would think that, as these two elements are connected , they would all rotate with the same angular velocity. If A rotates with a speed of 10rad/s it would be logical for me that point B just follows and rotates with the same angular velocity.
