(english) A vector quantity equal to the rate that position changes with time.
(english) A vector quantity equal to the rate that velocity changes with time.
(Software Engineering) the ability to reuse an already-existing program component in another application
(Software Engineering) a statement of basic requirements of the software to be built
(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) In this pump, the pistons are at an angle to the drive shaft and Thrust Plate. The piston block shaft is connected to the drive shaft by a universal joint, not shown. The drive shaft, thrust plate, piston block shaft, and piston block all revolve. The connecting rods are attached to the thrust plate and revolve with it, unlike the swash plate pump where the piston rods slide past a stationary swash plate. The outlet ports are semi-circular holes in the Valve Plate, shown on the far right of the animation on edge and in a head-on view below, right. As the pump revolves, half the pistons suck in fluid as they pass over the intake port. The other pistons discharge their fluid through the outlet port. This pump should be compared to the radial piston pump, swash plate pump, and wobble pump.
(english) The line of action of a force is the infinite line defined by extending along the direction of the force from the point where the force acts.

(english) Moment of inertia has two distinct but related meanings: 1) it is a property of a an object relating to the magnitude of the moment required to rotate the object and overcome its inertia. 2) A property of a two dimensional cross section shape with respect to an axis, usually an axis through the centroid of the shape.
(Software Engineering) a white box test case design technique that used the algorithmic flow of the program to design tests
(English) The top level of the boiler firebox where four oil guns are located. The oil guns are used to produce steam and maintain pressure while the boiler is on oil fire.
(english) Reversing the wrap of a coil putting the top surface on the bottom.
