gearbox

แปลว่าเกียร์รถ, เครื่องเปลี่ยนความเร็วของเครื่องยนต์ ที่เรียกกันทั่วๆ ไปว่า เกียร์ (ความหมายอย่างเดียวกับคำว่า change speed gear หรือ charge speed gear ซึ่งแปลว่า เครื่องถ่ายกำลังมาเป็นความเร็ว) กระปุกเฟืองเกียรร์)

Shear modulus:

แปลว่า(english) The ratio of shear stress divided by the corresponding shear strain in a linear elastic material.

Addendum

แปลว่า(english) That portion of a gear tooth that extends from the pitch circle to the outside diameter.

Defect removal efficiency (DRE)

แปลว่า(Software Engineering) a nondimension ratio (between 0 and 1) that provides an indication of the degree to which errors are removed from software before it is released to end-users

Temper

แปลว่า(Concrete Engineering) The addition of water to the cement mix whether at the batch plant, during transit or at the jobsite to achieve the specified water to cement ratio.

Brinell Hardness

แปลว่า(english) The hardness of a metal or part, as represented by the number obtained from the ratio between the load applied on the spherical area of the impression made by a steel ball forced into the surface of the material tested.

Ductility:

แปลว่า(english) Ductility generally refers to the amount of inelastic deformation which a material or structure experiences before complete failure. Quantitatively, ductility can be defined as the ratio of the total displacement or strain at failure, divided by the displacement or strain at the elastic limit.

Unit Water Content

แปลว่า(Concrete Engineering) The quantity of water per unit volume of freshly mixed concrete, often expressed as gallons or pounds per cubic yard. This is the quantity of water on which the water cement ratio is based, and does not include water absorbed by the aggregate

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.
