Spring Frequency Calculator to calculate natural frequency of a spring with a weight at lower
end. Spring is fixed from upper end and the lower end
is free. Natural frequency of spring mass system formula is $${ f }_{ 1 }=\frac { 1 }{ 2\pi } \sqrt { \frac { k }{ M } } $$.
Here k is spring constant and M is mass.
Note: Use dot "." as decimal separator.
RESULTS 
Mass M at lower end, spring weight negligible
