The cylinder is subjected to a load that has a weight W.
Chapter 8, Problem 8-131(choose chapter or problem)
The cylinder is subjected to a load that has a weight W. If the coefficients of rolling resistance for the cylinders top and bottom surfaces are aA and aB, respectively, show that a horizontal force having a magnitude of P = [W(aA + aB )]>2r is required to move the load and thereby roll the cylinder forward. Neglect the weight of the cylinder.
