		# FourBar
		A node.js program for a fourbar position analysis using the vector method. This library encompasses the angles of all the links and their position vectors along with the transmission angle.
		A node.js program for a fourbar position analysis using the vector method. This library encompasses the angles of all the links and their position vectors along with the transmission angle.

		#FourBar Position Analysis

		This library makes for quick and easy position analysis of a simple four bar linkage. Positions may be put through a simple derivative to obtain velocities and accelerations. For a better understanding of linkages and how to engineer linked mechanisms, see [Robert L. Norton's Design of Machinery](http://www.amazon.com/Design-Machinery-Robert-Norton/dp/0071215778). Inside this text are in depth explanations of linkages and their uses.

		##Methods

		\|Method call\|Parameters\|Description\|
		\|-----------\|----------\|-----------\|
		\|type\| N/A \| 'VectorMethod'\|
		\| linkageType \| inputLength, couplerLength, outputLength, groundLength \| Returns type of linkage \|
		\|couplerAngle \| inputLength, couplerLength, outputLength, groundLength, inputAngle \| Returns and __Object__ with __open__ and __crossed__ configuration angles of coupler link from the positive x-axis based on the input link angle in __Radians__ \|
		\|outputAngle \| inputLength, couplerLength, outputLength, groundLength, inputAngle \| Returns and __Object__ with __open__ and __crossed__ configuration angles of output link from the positive x-axis based on input link angle in __Radians__ \|
		\|couplerVector \| inputLength, couplerLength, outputLength, groundLength, inputAngle, deltaAngle \| Returns __Objects__ of the real and imaginary components of both the __crossed__ and __open__ configurations based on the input angle in __Radians__ + an optional __delta__ as seen below\|
		\|outputVector \| inputLength, couplerLength, outputLength, groundLength, inputAngle, deltaAngle \| Returns __Objects__ of the real and imaginary components of both the __crossed__ and __open__ configurations based on the input angle in __Radians__ + an optional __delta__ as seen below\|
		\|inputVector \| inputLength, couplerLength, outputLength, groundLength, inputAngle, deltaAngle \| Returns the real and imaginary components of the input link + an optional __delta__\|


		##Parameters


		In the image below, _input_ is represented by _s_, the _coupler_ is _p_ and the _output_ is _u_. Driving angle is _Theta 2_ and the _deltas_ are for creating ternary links.

		##Example

		Below is a vary basic example to show how fast calculations can be made

		var FourBar = require('../lib/vectorFourBar.js');
		var four = new FourBar;


		var output;
		var coupler;


		output = four.outputAngle(2, 7, 9, 6, 0.523599);
		coupler = four.couplerAngle(2, 7, 9, 6, 0.523599);

		console.log('');
		console.log('crossed output angle', (output.crossed * (180/Math.PI)));
		console.log('');
		console.log('open output angle', (output.open * (180/Math.PI)));
		console.log('');

		console.log('crossed coupler angle', (coupler.crossed * (180/Math.PI)));
		console.log('');
		console.log('open coupler angle', (coupler.open * (180/Math.PI)));
		console.log('');
		console.log('TYPE: ', four.linkageType(2, 7, 9, 6, 0.523599));
