Datum dimensioning is where a single reference point is used for all dimensions in a single direction. E.g. If Point A is declared the reference point, then Points B, C, D, etc, will all be measured relative to Point A, not to each other. Chain dimensioning is where each point is measured to the next. E.g. Point B is measured from Point A, Point C is measured from Point B, Point C is measured from Point B, and so on. The problem with chain dimensioning is that each measurement relies on the accuracy of the previous measurement. If there is a tolerance associated with each measurement (+/- X), then the tolerance for each subsequent dimension accumulates and becomes the number of measurements times the tolerance of each measurement (+/- n*X). Since datum dimensioning uses only one reference point, the tolerances cannot accumulate as each measurement is isolated, rather than relying on the accuracy of the previous measurement. Common practice is to only use datum dimensioning in design drawings to ensure greater accuracy over the entire design without requiring tighter tolerances.
A557 chain has a curved profile on the link sides. CA557 chain has straight profile on the link sides. Look at Allied-Locke document Catalog 39 to see the differences in link plate profiles.
polyhedron is often defined as a geometric object with flat faces and straight edges polygon is traditionally a plane figure that is bounded by a closed path or circuit, composed of a finite sequence of straight line segments (i.e., by a closed polygonal chain). .
The chain on a Kawasaki Mojove 250 ATV is adjusted by removing the chain cover and loosening the retaining bolts. The tensioner can then be turned until the chain reaches the desired tension.
A chain is a very old Linear Measure. 1 chain = 22 yards = 66 feet.
It show dimension of given dig. Ex. length meter etc. > chain dimensioning as opposed to datum dimensioning. chain dimensioning: 4 holes in line on a drawing, first hole position dimensioned from the edge, remainder dimensioned from the centre of the previous hole. datum dimensioning: all holes dimensioned from the edge. the cumulative tolerance build up on the chain dimensioning allows for greater overall tolerance build up.

The difference between a chain printer and a band printer is a chain printer has a chain that the characters are on and a band printer has a band for the characters.

Sprocket and chain and what?
There isn't a big difference between the food chain and food web. This is just a different way of drawing out the same concept.
The difference between a mountain range and a mountain chain is that a mountain chain is a row of mountains and a mountain range is lots of mountains in one area.

The difference is a boutique hotel is more exclusive & private than a chain hotel.
the difference is that a food chain is smaller then a food web because a food web is more animals then a food chain
chain in inside the engine and the belt is outside
hotel chain is owned by a group of owners
