Homework Statement
Dont need to read the problem, just copied it on for the figure:
So a plank rests on top of two identical cylindrical rollers - rolling without slipping both between cylinders and plank, and cylinders and surface.
My book says that center of each roller moves forward only half as far as the plank - why is this?
Is it because there are two rollers? Because doesn't a point R away from center of rollers move as far as the center does when we have rolling without slipping? [/B]
