Calculation of compression coil springs

* This app allows you to calculate the compression coil springs.

* The calculation method used is based on the equations and procedures used by Faires in the book "Design of machine elements".

* Use 2 calculation modes:
   - Testing mode of existing springs.

   -Design mode to define necessary spring size.

* It has a database of materials most used for springs, with the admissible and closing resistances for each diameter and type of service for a maximum diameter of 12.7mm.

* In entering design mode, enter:
 -Type of extremes
 -Material
 -Type of service
 -Force
 -Deformation
 -Internal required diameter of the spring
 -Longitude free
* The results in this mode are the following:
 -Numero of gauge and diameter of wire
 - Average diameter between turns
 -Constant spring (K)
 -Travel
 -Closed length
 -Angle of the turns
 - Tension under the load and admissible tension of the material for that diameter of wire
 - Tension when closing it completely and closing tension that supports the material for that wire diameter
 -Stored energy
 Closing force
 -Step of the turns
 -Number of active turns
 -Number of total turns
 -Natural frequency
 -Dough
 -Overall observations (possibility of buckling, care in bending of turns, tension of material)

* In the verification mode, enter:
 -Type of extremes
 -Material
 Type of use
 -Wire diameter
 -Force
 -Diameter average
 -He passed
 -Number of total turns

* The results obtained in the verification mode are the following:
 -Deformation of the spring
 -Constant spring K
 -Stored energy
 -Travel
 -Longitude free
 -Closed length
 -Close force
 -Inner diameter of the coil
 - Tension under the load and admissible tension of the material for that diameter of wire
 - Tension when closing it completely and closing tension that supports the material for that wire diameter
 -Angle of the turns
 -Number of total active turns
 -Natural frequency
 -Dough
 -Overall observations (possibility of buckling, care in bending of turns, tension of material)
