Back-up Balance

Roller support:

(english) In two dimensions, a roller support restrains one translation degree of freedom.

Support:

(english) A support contributes to keeping a structure in place by restraining one or more degrees of freedom. In a structural model, supports represent boundary entities which are not included in the model itself, e.g., foundations, abutments, or the earth itself. For each restrained translation degree of freedom at a support, there is a corresponding reaction force; for each restrained rotation degree of freedom, there is a reaction moment.

Pin support:

(english) In two dimensions, a pin support restrains two translation degrees of freedom but does not restrain rotation. When considering reaction forces, a pin support is usually considered to have two force components: one each about the x and y axes respectively.

Independent test group (ITG)

(Software Engineering) a group of people whose primary responsibility is software testing

Couple:

(english) A system of forces composed of two equal forces of opposite direction, offset by a distance. A couple is statically equivalent to a moment whose magnitude equals the magnitude of the force times the offset distance.

upstream blanket

Fixed support:

(english) In two dimensions, a fixed support restrains three degrees of freedom: two translations and one rotation.

Backer (back-up plate)

(english) A “tool” or reinforcing part, which presses against the outer surface of an extrusion die, supporting it against the pressure of the extruding metal. The backer has an opening larger than the die aperture, allowing the extruded product to emerge without marring its soft surface.

uplift pressure

แรงดันขึ้นของน้ำ : ดู [[pressure]], [[uplift]]

Back-up Roll

(english) 1) Roll used as a support roll mainly for plater rolls. 2) Two rolls, one on top and one on bottom of the two work rolls which apply pressure and reduce the flexing of the work rolls.
