Title: How to measure friction coefficient
Post by: Fu-Kwun Hwang on June 08, 2005, 09:08:06 am
If you want to know the friction coefficient for a block on a surface.
1. Put the block on the horizontal surface
2. Raise one end of the surface. record the angle (cta) when the block starts moving
3. the friction coefficient = tan(cta)
Drag the slider on the left to change the angle of the ramp.
