Flexibility:

แปลว่า(english) Flexibility is the inverse of stiffness. When a force is applied to a structure, there is a displacement in the direction of the force; flexibility is the ratio of the displacement divided by the force. High flexibility means that a small load produces a large displacement.

Stiffness:

แปลว่า(english) This is a general term which may be applied to materials or structures. When a force is applied to a structure, there is a displacement in the direction of the force; stiffness is the ratio of the force divided by the displacement. High stiffness means that a large force produces a small displacement. When discussing the stiffness of a material, the concept is the same, except that stress substitutes for force, and strain substitutes for displacement; see modulus of elasticity.

Back-up Balance

แปลว่า(english) Cylinders that supply the force used to hold the back-up rolls up in place.

Colloids

แปลว่า(Environmental Engineering) Small particles which have a negligible settling velocity. These particles have a very small mass so gravitational force is low compared to surface frictional forces. Typical colloidal sizes range from 10-3 mm to 1 mm.

Bright Dip

แปลว่า(english) An acid solution into which pieces are dipped in order to obtain a clean, bright surface.

Blue Vitriol Copper sulfate

แปลว่า(english) A layout solution which turns a copper color when applied to a clean,polished metal surface.

Bruise

แปลว่า(english) A mark transferred to the strip surface from a defective process roll. Similar to dent or punchmark.

Bright Annealing

แปลว่า(english) A process carried out usually in a controlled furnace atmosphere, so surface does not oxidize, remaining bright.

Activation

แปลว่า(english) The changing of the passive surface of a metal to a chemically active state. Contrast with passivation.

Peeling

แปลว่า(Concrete Engineering) A process in which thin flakes of matrix or mortar are broken away from concrete surface; caused by adherence of surface mortar-to forms as forms are removed, or to trowel or float in portland cement plaster.

Pining

แปลว่า(Concrete Engineering) Development of relatively small cavities in a concrete surface, due to phenomena such as cavitation or corrosion.

Bright Annealing 2

แปลว่า(english) The process of annealing in a protective atmosphere so as to prevent discoloration of the bright surface desired.
