Weight:

(english) The force on an object resulting from gravity.

Reaction:

(english) A reaction is a force exerted by a support on an object: sometimes called support reaction. Using this definition, a reaction is an external force.

Shear:

(english) An system of internal forces whose resultant is a force acting perpendicular to the longitudinal axis of a structural member or assembly: sometimes called shear force.

Blow

(english) The impact or force delivered by one workstroke of the forging equipment.

Stress:

(english) The intensity of internal force acting at a point in an object. Stress is measured in units of force per area. See shear stress and normal stress.

e.m.f

อักษรย่อจากคำว่า electromotive force = แรงเคลื่อนไฟฟ้า, กำลังดันไฟฟ้า (ใช้เป็นหน่วยโวลท์)

Flexibility:

(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:

(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

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

Statically equivalent:

(english) Two force systems are statically equivalent when their resultants are equal. Physically, this means that the force systems tend to impart the same motion when applied to an object; note that the distribution of resulting internal forces in the object may be different.

Energy:

(english) A property of a body related to its ability to move a force through a distance opposite the force's direction; energy is the product of the magnitude of the force times the distance. Energy may take several forms: see kinetic energy, potential energy, and elastic energy.
