WebStick-slip is the alternate sticking and slipping which occurs when partially lubricated slides operate at low speed. This produces a saw-tooth form of friction force variation in the stick–slip range illustrated by the graph, Figure 6.16.Under these conditions a machine-tool slide will remain stationary until the feed force has reached a magnitude sufficient to … WebOct 16, 2002 · Friction is a very complicated phenomenon arising at the contact of surfaces. Experiments indicate a functional dependence upon a large variety of parameters, including sliding speed, acceleration, critical sliding distance, temperature, normal load, humidity, surface preparation, and, of course, material combination. In many engineering … WebThis doesn't sound like a particularly likely reason for similar pieces of plastc to stick, since they'd typically pick up the same sign of charge, and thus repel. ... charging glass via friction.
