## Homework Statement

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.

## Homework Equations

va = vb + va/b

velocity at edge of circle in line with O = sqrt(2)*v

Vc = 0

## The Attempt at a Solution

[/B]

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.
