Java spring calculation and plotting programme

This program can be used in two ways:

1. To calculate the stresses in a spring which has been specified by entries in the in the top 8 boxes on the left, in the units indicated. After entering the values click on the Calculate button.

2. To calculate the stiffness of an existing spring. Enter values only for the, shear modulus, coil and wire mean diameters and (in the top right box) the existing number of turns, then click on Calculate stiffness button. The result appears in the Calculated rate box.
