What is meant by stick-slip?
Definition of stick-slip : movement of two surfaces relative to each other that proceeds by a series of jerks caused by alternate sticking from friction and sliding when the friction is overcome by an applied force.
What is the stick and slip process?
Stick slip refers to the fast movement that occurs between two sides of a fault when the two sides of the fault become unstuck. The rock becomes distorted, or bent, but holds its position until the earthquake occurs. When the rock snaps back into an unstrained position it is called elastic rebound.
What causes stick-slip?
Stick-slip is a common phenomenon that can occur in seals due to uneven friction between objects sliding across each other. This repetitive start-stop movement or vibration known as stick-slip can cause major issues and even failure of mechanical systems, including seals.
What is an example of stick-slip motion?
Stick–slip occurs in many situations where frictional excitation is present, for example a violin bow acting on the string.
What is stick-slip in hydraulic cylinders?
In the area of seals and cylinders, Stick-slip is characterized by a distinct stop-start movement of the cylinder, and may be so rapid that it resembles severe vibration, high pitched noise or chatter. Seals are often thought to be the source of the stick-slip, but other components or hardware can create this issue.
Who developed slip stick?
This is a simple laboratory demonstration of the stick-slip phenomenon, so named in 1939 by F. P. Bowden and L. L. Leben, physical chemists at the University of Cambridge, who built an apparatus to study the process. [see chart at lower right on page 112].
What are faults types?
There are four types of faulting — normal, reverse, strike-slip, and oblique. A normal fault is one in which the rocks above the fault plane, or hanging wall, move down relative to the rocks below the fault plane, or footwall. A reverse fault is one in which the hanging wall moves up relative to the footwall.
What three conditions are needed for stick-slip motion?
The three conditions for stick-slip motion are: (1) two objects that are touching each other where at least one of the objects can move, (2) a force, or forces, that will cause the movement, (3) friction strong enough to temporarily keep the moving from starting.
Is static friction?
Static friction is a force that keeps an object at rest. Static friction definition can be written as: The friction experienced when individuals try to move a stationary object on a surface, without actually triggering any relative motion between the body and the surface which it is on.
What does a low coefficient of friction mean?
The coefficient of friction, µ, is a measure of the amount of friction existing between two surfaces. A low value of coefficient of friction indicates that the force required for sliding to occur is less than the force required when the coefficient of friction is high.
