When you enter the required inputs and click "calculate" a new window will appear containing the torques and stresses that your spring will generate.  The torques and stresses will be given for a number of radial deflection values between 0 and 360.  The number of deflection values displayed is controlled by the input labeled i "increment".  The program will start with 0 deflection and calculate the torques and stresses.  Then the spring deflection is repeatedly increased by the "increment" value, with torques and stresses calculated for each radial deflecton.

In addition, there is an optional input Fw "working deflection" that is used to force the program to calculate torques and stresses at a specific radial deflection that you are interested in.  The value will be entered into the same chart that contains all of the other increments, but will be displayed in bold with a next to it.

With this unique tool, iterative design becomes easier since you can tell by looking at the table how the torques and stresses are varying with deflection.  You can leave multiple results windows open for comparison since the window will not close when you submit new inputs.

Finally, once you've decided on a design, you can get the complete documentation by clicking on it's deflection value.  A new window will open with text that you can copy and paste into your word processing software.

Note: The "Corrected Stress" values given in the results table (Sadj) takes into account the increased stress on the inside of the section due to curvature and is obtained ONLY for use in comparison with your allowable working stress.  Do not use this value for use in other formulas, but use the calculated Stress S instead.
