Input interpretation:

maximum spring force


Equation:

F_max = (E d^4 (L - n d))\/(16 (1 + nu) (D - d)^3 n) |  \nF_max | maximum spring force\nD | spring outer diameter\nd | spring wire diameter\nL | free length of spring\nE | Young\'s modulus\nnu | Poisson ratio\nn | number of active windings\n(force of fully compressed spring)


Input values:

spring outer diameter | 1 cm  (centimeter)\nspring wire diameter | 2 mm  (millimeters)\nfree length of spring | 50 cm  (centimeters)\nYoung\'s modulus | 211 GPa  (gigapascals)\nPoisson ratio | 0.3\nnumber of active windings | 5


Result:

maximum spring force | 31.07 kN  (kilonewtons)\n= 6984 lbf  (pounds-force)\n= 31067 N  (newtons)
