Calculator
This calculator computes the force exerted by a compression spring (with a known spring constant k) when given the spring length before and after loading.

Inputs
  Spring free length, Lfree:    
  Spring length when deformed, Ldef:    
  Spring constant, k:    
Answer
  Force exerted by spring, F:  2.50  lbf
 
Equations Behind the Calculator
The force in the compression spring is found from Hooke's Law,
