In materials science, slip is the large displacement of one part of a crystal relative to another part along crystallographic planes and directions. [1] Slip occurs by the passage of dislocations on close/packed planes, which are planes containing the greatest number of atoms per area and in close-packed directions (most

Therefore, compressive stress in the direction perpendicular to the half plane promotes positive climb, while tensile stress promotes negative climb. This is one main difference between slip and climb, since slip is caused by only shear stress. One additional difference between dislocation slip and climb is the temperature dependence.
Peierls stress (or Peierls-Nabarro stress, also known as the lattice friction stress [1]) is the force (first described by Rudolf Peierls and modified by Frank Nabarro) needed to move a dislocation within a plane of atoms in the unit cell.

A blocked rotor test is conducted on an induction motor.It is also known as short-circuit test (because it is the mechanical analogy of a transformer short-circuit test), [1] locked rotor test or stalled torque test. [2]
To assess a floor's slip resistance, a reliable, thoroughly researched (in interlaboratory studies) floor friction test method must be used, and then a minimum safety criterion (0.42, 0.60, 36, etc.) is needed to apply to the results. Each different slip test device will have its own safety criterion.
A litter of two-week old puppies was crammed into a bucket and abandoned alongside a road in Union County, New Jersey on Thursday, police said.
