In geometry and mechanics, a displacement is a vector whose length is the shortest distance from the initial to the final position of a point P undergoing motion. [1] It quantifies both the distance and direction of the net or total motion along a straight line from the initial position to the final position of the point trajectory.
Engine displacement, the total volume of air/fuel mixture an engine can draw in during one complete engine cycle; Displacement (fluid), an object immersed in a fluid pushes the fluid out of the way; Positive displacement meter, a pump or flow meter which processes a definite fluid volume per revolution
Engine displacement is the measure of the cylinder volume swept by all of the pistons of a piston engine, excluding the combustion chambers. [1] It is commonly used as an expression of an engine's size, and by extension as an indicator of the power (through mean effective pressure and rotational speed ) an engine might be capable of producing ...
Standard displacement, also known as "Washington displacement", is a specific term defined by the Washington Naval Treaty of 1922. [11] "It is the displacement of the ship complete, fully manned, engined, and equipped ready for sea, including all armament and ammunition, equipment, outfit, provisions and fresh water for crew, miscellaneous ...
[5] [6] If is the initial position of an object and is the final position, then mathematically the displacement is given by: = The equivalent of displacement in rotational motion is the angular displacement measured in radians. The displacement of an object cannot be greater than the distance because it is also a distance but the shortest one.
Absement changes as an object remains displaced and stays constant as the object resides at the initial position. It is the first time-integral of the displacement [3] [4] (i.e. absement is the area under a displacement vs. time graph), so the displacement is the rate of change (first time-derivative) of the absement.
Strain can be formulated as the spatial derivative of displacement: = ′, where I is the identity tensor. The displacement of a body may be expressed in the form x = F ( X ) , where X is the reference position of material points of the body; displacement has units of length and does not distinguish between rigid body motions (translations and ...
In physics and continuum mechanics, deformation is the change in the shape or size of an object. It has dimension of length with SI unit of metre (m). It is quantified as the residual displacement of particles in a non-rigid body, from an initial configuration to a final configuration, excluding the body's average translation and rotation (its rigid transformation).
