a wheel 2cm wide with a 3.5cm radius is being spun at a constant velocity "w" by a static force "F"

if a bar also 2cm wide and of mass m, is set on top of the wheel so it contacts only at a small tangent the coefficient of sliding friction is measured to be .48

how much work is being 'lost' through the bar?
