1. The problem statement, all variables and given/known data A wheel of radius 42 mm is rolling without slipping and its centre O has a velocity 7.2 m/s in the direction shown. The slider B is driven by the link AB and A is connected to the wheel. If AC= 28.9 mm, AB= 73.9 mm and angle ACB= 73°, what is the velocity of the slider B? Take the right-hand side direction positive. 2. Relevant equations va = vb + va/b velocity at edge of circle in line with O = sqrt(2)*v Vc = 0 3. The attempt at a solution My initial thoughts are that B first has to move to the left as A is going to pull it rather than push. (So the answer will be negative) I first constructed the triangle ABC, but without angle CAB or side CB, I don't know how to complete it. Any help would be greatly appreciated, Thanks.
