Cutting is the separation of a physical object, or a portion of a physical object, into two portions, through the application of an acutely directed force. An implement commonly used for cutting is the knife or in medical cases the scalpel. However, any sufficiently sharp object is capable of cutting if it has a hardness sufficiently larger than the object being cut, and if it is applied with sufficient force. Cutting also describes the action of a saw which removes material in the process of cutting. Image File history File links Information. ... This article or section does not adequately cite its references or sources. ... A scalpel is a very sharp knife used for surgery, anatomical dissection, and various arts and crafts. ... In materials science, hardness is the characteristic of a solid material expressing its resistance to permanent deformation. ... Portable saw A saw is a tool for cutting wood or other material, consisting of a serrated blade (a blade with the cutting edge dentated or toothed) and worked either by hand or by steam, water, electric or other power. ...

Cutting is a compressive and shearing phenomenon, and occurs only when the total stress generated by the cutting implement exceeds the ultimate strength of the material of the object being cut. The simplest applicable equation is stress = force/area: The stress generated by a cutting implement is directly proportional to the force with which it is applied, and inversely proportional to the area of contact. Hence, the smaller the area (i.e., the sharper the cutting implement), the less force is needed to cut something. Physical compression is the result of the subjection of a material to compressive stress, resulting in reduction of volume. ... In physics and mechanics, shear refers to a deformation that causes parallel surfaces to slide past one another (as opposed to compression and tension, which cause parallel surfaces to move towards or away from one another). ... Stress is the internal distribution of force per unit area that balances and reacts to external loads applied to a body. ... Strength of materials is materials science applied to the study of engineering materials and their mechanical behavior in general (such as stress, deformation, strain and stress-strain relations). ...

When refering to propagating plants, cutting is one of the methods that can be used. It involves cutting a part of the plant typically a healthy shoot, with sharp and sterile scissors or any other cutting device, and then placing the removed part in water. Some cuttings do not require water. Certain shoots when cut are able to grow when placed in vermiculite or potting soil. However, the former is the easiest to do as most shoots when cut from the main plant need time to grow roots, and then they are able to be transferred to potting soil.

Jump cut - Wikipedia, the free encyclopedia (589 words)
A jump cut is a cut in film editing where the middle section of a continuous shot is removed, and the beginning and ends of the shot are then joined together.
A generic example of a jump cut is a shot in which two actors are talking to each other, with one having his or her hands at her sides.
Jump cuts are generally either a technical flaw, or done for an artistic special effect — most normal cuts in film editing occur between dissimilar scenes or significantly different views of the same scene to avoid the appearance of a jump.
G.O.P. to Seek Cut in Capital Gains Tax (992 words)
If enacted, the cut in the capital gains tax rate, which applies to profits on the sale of stock and other assets held for more than a year, would give a break to the growing legions of individual investors.
The top capital gains rate was last cut, to 20 percent from 28 percent, as part of the 1997 bipartisan tax and budget deal.
The tax cuts would be phased in as the projected surpluses grow, with $5 billion available for tax cuts next year and $200 billion over the first five years, Archer said.
