• Excessive seal friction wastes energy, accelerates wear, and can lead to premature failure. • Too little friction makes a seal prone to leak. • Pressure-activated hydraulic seals minimize both ...
A cook's reaction to cockroaches in the kitchen is a good approximation of a physicist's reaction to friction: not only is it undesirable, it is hard to get rid of. OK, our analogy falls at a last ...
Friction is an intrinsic physical phenomenon to curling. Without it, objects in motion would move endlessly, without slowing down. This would cause many safety-related problems: Cars or trains could ...
Friction may not be the first problem we think of afflicting medical device design, but it is a real issue for many single-use medical devices like syringes, injection pens, and auto-injectors.
