Re: Friction Steel Clamp calculation

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Going back to my old physics lab, friction force is not a function of
surface area.  It is the clamping force times the coefficient of friction.
Adheresion is a function of surface area.  I'm not familiar with the term
'friction stress'.
