Coefficient of friction metal on metal
WebMar 12, 2024 · Using a sort of average from these graphs, we're using 0.25 as the coefficient, but of course this is dynamic and lower than the static friction number would be. Extremely close to meeting our design goal, like by several mph..... A value > 0.31 static would get the job done, so close....

WebUltimately, I think the discrepancies you are seeing are due to differences in conditions. As you probably know, the conditions can change the coefficient of friction enormously. … WebApr 8, 2024 · The coefficient of friction decreases with increasing lubricant pressure for contact pressures of 2–6 MPa. For a contact pressure of 8 MPa, the lubricant pressure is the least favorable for reducing the coefficient of friction.
WebCoefficient of Friction Equation or Table Figure Design Resources Friction Design Data Who frictional force for Statistic Friction can shall expression as: F max = μ F n where F max = Slip force (N, lb) μ = static (μ s ) or kinetic (μ k ) frictional coefficient F n = Applied Normal force (N, lb) WebIt solely depends on the materials, the surfaces and, of course, which case of friction you're looking at (static or dynamic). Google spat out some coefficient tables that clearly contain values larger than one mostly for same type metal on metal friction. I doubt there's a theoretical limit on it, at some point the model just doesn't fit anymore.
