straight-line mechanism
1Straight line mechanism — In the late seventeenth century, before the development of the milling machine, it was extremely difficult to machine straight, flat surfaces. For this reason, good prismatic pairs without backlash were not easy to make. During that era, much… …
2straight-line — [strāt′līn΄] adj. 1. composed of straight lines 2. Finance designating or of a method of allocating costs to given time periods at a fixed rate [straight line depreciation] 3. Mech. a) designating or of a device, mechanism, etc. whose main parts… …
3straight-line — ˈ ̷ ̷| ̷ ̷ adjective 1. : being a mechanical linkage or equivalent device designed to produce or copy motion in a straight or approximately straight line 2. a. : having the principal parts arranged in a straight line a straight line compressor… …
4straight-line — /strayt luyn /, adj. 1. Mach. a. noting a machine or mechanism the working parts of which act or are arranged in a straight line. b. noting a mechanism for causing one part to move along a straight line. 2. Accounting. denoting uniform allocation …
5Mechanism (engineering) — A mechanism is a device designed to transform input forces and movement into a desired set of output forces and movement. Mechanisms generally consist of moving components such as gears and gear trains, belt and chain drives, cam and follower… …
6reaction mechanism — Introduction in chemical reactions (chemical reaction), the detailed processes by which chemical substances are transformed into other substances. The reactions themselves may involve the interactions of atoms (atom), molecules (molecule),… …
7slider-crank mechanism — ▪ mechanics arrangement of mechanical parts designed to convert straight line motion to rotary motion, as in a reciprocating piston engine, or to convert rotary motion to straight line motion, as in a reciprocating piston pump. The basic nature… …
8Non-line-of-sight propagation — Non line of sight (NLOS) or near line of sight is a term used to describe radio transmission across a path that is partially obstructed, usually by a physical object in the innermost Fresnel zone. Many types of radio transmissions depend, to… …
9Crank (mechanism) — A crank is an arm attached at right angles to a rotating shaft by which reciprocating motion is imparted to or received from the shaft. It is used to change circular into reciprocating motion, or reciprocating into circular motion. The arm may be …
10eccentric-and-rod mechanism — ▪ mechanics arrangement of mechanical parts used to obtain a reciprocating straight line motion from a rotating shaft; it serves the same purpose as a slider crank mechanism and is particularly useful when the required stroke of the… …
