What is the difference between edge and screw dislocations?
The main difference is: The slip vector ( Burger's vector) and the line vector, which is line of atoms that dislocated, are perpendicular to each other in case of edge dislocation. In case of screw dislocation, they are parallel to each other.
Where defects can occur in crystal structures?
Within a crystal there are point defects and line defects; point defects are missing or extra lattice points within the crystal lattice (vacancies or interstitials), line defects may be due to an 'extra' half lattice plane within the crystal. The end of a line defect plane is known as an edge dislocation, screw dislocations occur where part of a crystal is displaced over one lattice direction and is therefore twisted. Dislocation loops can occur where an edge and a screw dislocation intersect.
Why does a Screw takes less forces to move into wood than a nail?
a screw possesses both rotational kinetic energy and translational kinetic energy while a nail possesses only translational kinetic energy as it moves through the piece of wood hence the screw moves faster since its motion is backed by more energy than the nail.
What is pitch of the screw?
The pitch is the axial distance between threads, and the distance the thread moves with a 360 degree revolution. So if the pitch of a screw is 1mm, one revolution will move it 1mm farther down.
What kind of simple machine is a chair?
A chair is not a simple machine unless it is a swivel chair that moves due to a screw, A screw is an example of a simple machine. Some other examples are wheel and axle, wedge, and pulley.

What is difference between cross slip vs slip?
Dislocations move because the resolved shear stress (Schmidfactor) is sufficient high enough to activate the glide system in which the slip plane lies. (slip) Screw-dislocations in fact are able to move from one slip plane to another parallel plane (burgers vector does not change!). In a fcc lattice a $dislocation may change the (111) plane to (1 -1 1) plane due to local stresses. (cross slip) Edge dislocations can change their planes too. It is a thermally activated process which is called climb (vacancy flux).
How do you get into optical field?
an optical vortex (also known as a screw dislocation or phase singularity) is a zero of an optical field, a point of zero intensity. Research into the properties of vortices has thrived since a comprehensive paper by Nye and Berry, in 1974,[1] described the basic properties of "dislocations in wave trains". The research that followed became the core of what is now known as "singular optics".
Which screw will rust faster an iron screw or a metal screw?
of course it is the iron screw because it is made up of minerals that rust faster then metal

What cleats are faster rubber cleats or screw on cleats?
As a DB and WR I can only say I'm faster with screw on cleats ;)
How does the number of threads on a screw affect the distance the screw moves?
the threads determine the depth the screw should move
What is the difference between Screw driven and hydraulic driven tensile testers?
A screw drive is a screw mechanism that moves and hydraulics is a fluid pressure system
Why is a screw called an inclined plane?
A screw is called an inclined plane because it is. The only difference between a screw and an inclined plane is the way they look and how they work. A screw is an inclined plane that moves.
What does the Archimedes water screw do?
It moves water, much like a pump.
Why is a faucet handle a screw?
When you shut the faucet off, the screw pushes a rubber washer against the opening inside the faucet and stops the water. The screw moves in and out in the handle to do this.
