How much work is being ''lost'' through the bar

Reference no: EM13499244

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
