  1. Lest Ye Jam Problem:Bushings may jam when assembled on pegs, as a result of the two contact points creating more oppositional friction force than the assembly force applied. Common Jam Scenarios Battery Lid Assembly Bushing/Washer being Assembled onto a Peg Piston Assembly in an Cylinder Sleeve Multiple Hole alignment Bolt-Action Rifle Changing Wheels on a Car Design Equation for Preventing Jams By summing forces and moments around the origin, this equation was derived to relate the dimensions of the assembly so a single calculation can be done to pick the correct size parts. As long as the inequality is satisfied the assembly will be jam free. 1+L2>(1-C)2(μ2+1) L = Thickness of Part being assembled on Peg C = Difference in the inside diameter of Part and outside diameter of Peg μ = Coefficient of Friction between the Part and Peg Example Graphical representation of a washer jamming on a bolt with a coefficient of friction of 0.75. The line shows the case when the above equation is set equal (where c is at its minimum value for a given L to insure no jamming). Jon Dunais Matt Herset Whitney Menzel Taylor Tinsley
