Abstract
Experiments are conducted to determine coefficients of rolling resistance by rolling disk-shaped wheels of Teflon, poly(methyl methacrylate) and steel on a smooth, flat and horizontally levelled surface of steel. Normal load, diameter and wheel material are varied. The coefficient of rolling resistance for a slow moving wheel is found to depend only on a dimensionless number N (ER) , where N is the normal load per unit width of the wheel, R is its radius and E is the equivalent modulus of the wheel and the flat surface over which it rolls. A theoretical model based on the strain energy in the rolling elements is developed and compared with the experimental results.
