Equivalent stiffness of spring for series combination:
$(\frac{1}{{{S_{eq}}}} = \frac{1}{{{S_1}}} + \frac{1}{{{S_2}}})$
$(\frac{1}{{{S_{eq}}}} = \frac{{({S_1} + {S_2})}}{{{S_1}{S_2}}})$
$({S_{eq}} = \frac{{{S_1}{S_2}}}{{({S_1} + {S_2})}})$
Equivalent stiffness of spring for parallel combination:
Seq = S1 + S2
$(\frac{1}{{{S_{eq}}}} = \frac{1}{{{S_1}}} + \frac{1}{{{S_2}}})$
$(\frac{1}{{{S_{eq}}}} = \frac{{({S_1} + {S_2})}}{{{S_1}{S_2}}})$
$({S_{eq}} = \frac{{{S_1}{S_2}}}{{({S_1} + {S_2})}})$
Equivalent stiffness of spring for parallel combination:
Seq = S1 + S2
