1. The problem statement, all variables and given/known data 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 2. Relevant equations Va = Vb + Wba x Ra/b 3. 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?
