When static friction isn't enough, the friction becomes dynamic friction and slipping happens.
2.
Note that " ? " can be the coefficient for static or dynamic friction.
3.
Conversely, if the force falls outside the cone, static friction gives way to dynamic friction.
4.
Efficiency is generally high, because most of the dynamic friction is caused by very slight transitional clutch speed changes.
5.
Since static friction is greater than dynamic friction for almost all materials-this is the best you can do for maximum accelleration.
6.
Finally, dynamic friction prevails and the torque is distributed in a 50 / 40 / 10 % manner as the bolt is tensioned.
7.
Pile on more spheres and the contact stresses increase, to the point of causing frictional instability ( dynamic friction ), and perhaps failure.
8.
Once the angle is sufficiently steep, gravity overcomes static friction and dynamic friction comes into play .-talk ) 04 : 25, 20 February 2008 ( UTC)
9.
It even fails to take account of the wildly different numbers you get for static and dynamic friction ( a critical factor in answering this very question in fact ).
10.
If this water is removed, by extreme drying, the rock minerals do not behave at all as expected : they exhibit no " fault healing " or dynamic friction.
