Homework Statement



At the instant shown, bar AB has a constant angular velocity of 25 rad/s counterclockwise. Dtermine at that instant a) the angular velocity of the rectangular plate FBDH, b) the velocity of point F

Homework Equations



Va = Vb + Wba x Ra/b

The Attempt at a Solution



Found Vb with the above formula which equals to 507.5j. And i think i should use the instantaneous centre of rotation method but i dont know how to find it.
Can anyone help me to solve this problem?

Hi 385sk117! :smile:

Do you mean you don't know how to find the instantaneous centre of rotation?

You know that B is moving perpendicular to AB, and D is moving perpendicular to DE. :wink:
