I promised to bring two bottles of booze to the party.
(english) The bottom level of the boiler firebox where two oil guns are located. The oil guns are used if the boiler needs extra steam while on oil fire.
(english) A directed interaction between two objects that tends to change the momentum of both.Since a force has both direction and magnitude, it can be expressed as a vector
Did you see those two people cutting in front of us in line just now? Let's cut in front of them and give them a taste of their own medicine!
(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.
The honcho says that we are going to have to give up two days of our vacation.
(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.
บันไดที่ทำเป็นตอนหรือทอดหนึ่ง, บันไดหนึ่งทอดถึง apair of steps บันไดหนึ่งทอดถึง one pair back ห้องชั้นบนข้างหลังที่ขึ้นบันไดทอดเดียวถึง one pair front ห้องชั้นสองข้างหน้าที่ขึ้นบันไดทอดเดียวถึง (ถ้าเป็นห้องชั้นสามข้างหน้าใช้ two pair front หรือชั้นสี่ ใช้ tree pair back front)
(Environmental Engineering) A submicroscopic genetic constituent which can alternate between two distinct phases. As a virus particle, or virion, it is DNA or RNA enveloped in an organic capsule. As an intracellular virus, it is viral DNA or RNA inserted into the host organisms DNA or RNA.
(english) Similar to the concept of center of gravity, except that it applies to a two dimensional shape rather than an object. For a given shape, the centroid location corresponds to the center of gravity for a thin flat plate of that shape, made from a homogeneous material.
(english) An attractive force between two objects; each object accelerates at a rate equal to the attractive force divided by the object's mass. Objects near the surface of the earth tend to accelerate toward the earth's center at a rate of ; this value is often called the gravitational constant and denoted as g.
(english) Strain measuring the intensity of deformation along an axis. Normal strain is usually denoted by . Average normal strain between two points is calculated as (Delta L / L), where L is the original distance between the points, and L is the change in that distance. Normal strain is often simply called strain.
