A cycle test is done on a set of products (>20) until 10% of the units under test fail.
The number of cycles is converted to a time period by knowing the cycles per hour in any particular application.
A failure rate is calculated by dividing the 10% failure…
What is Stiction?
Stiction is the resistance to the start of motion usually measured as the difference between the external force being applied in order to overcome the static friction and the force to maintain movement between the two contacting or working surfaces.
It can…

Stiction is a phenomenon that is beginning to become an accepted theory among engineers. It…
Many studies and organizations have defined stiction, or static friction, in different ways. A few examples of the various definitions are as follows:
