Let y f x be a function. Different types of math transformation there are different types of math transformation one of which is the type y f bx. This compression ratio calculator can be used to work out the compression ratio of your engine. Vertical compression means making the y value smaller for any given.

Now to vertically compress this curve you put a fraction coefficient in front of the x component of the graph. Mathematics behind image compression. 2 undergraduate student hostos community college. This type of math transformation is a horizontal compression when b is greater than one.

The compression ratio is the ratio between two elements. 1 assistant professor of mathematics department of mathematics hostos community college the city university of new york usa. If the constant is between 0 and 1 we get a vertical compression. The gas volume in the cylinder with the piston at its highest point top dead center of the stroke tdc and the gas volume with the piston at its lowest point bottom dead center of the stroke bdc.

F x 1 2 x 2. The graph below shows a function multiplied by constant factors 2 and 0 5 and the resulting vertical stretch and compression. 1 2 corresponds to a a compression of y 1 2 in the x direction by a factor of 3 followed by a shift in the. Poisson s ratio is a measure of the poisson effect that describes the expansion or contraction of a material in directions perpendicular to the direction of loading the value of poisson s ratio is the negative of the ratio of transverse strain to axial strain for small values of these changes is the amount of transversal expansion divided by the amount of axial compression.

If the constant is greater than 1 we get a vertical stretch. This squashes the graph down by a factor of 2. In the above function if we want to do horizontal expansion or compression by a factor of k at every where of the function x co ordinate has to be multiplied by the factor k. 113 3161 redmond wa 98052 email.

Or another way to look at it every y value in this curve is 1 2 of the value in the starting curve. The function y 2 e01.
