Combined Stiffness of Two Springs Connected in Series Solution

STEP 0: Pre-Calculation Summary
Formula Used
Equivalent Spring Stiffness = Stiffness of 1st Spring*Stiffness of 2nd Spring/(Stiffness of 1st Spring+Stiffness of 2nd Spring)
Keq = K1*K2/(K1+K2)
This formula uses 3 Variables
Variables Used
Equivalent Spring Stiffness - (Measured in Newton per Meter) - Equivalent Spring Stiffness is the single stiffness of spring obtained by combining different spring constants.
Stiffness of 1st Spring - (Measured in Newton per Meter) - Stiffness of 1st Spring is the force per unit length required to deflect the first spring.
Stiffness of 2nd Spring - (Measured in Newton per Meter) - Stiffness of 2nd Spring is the force per unit length required to deflect the second spring.
STEP 1: Convert Input(s) to Base Unit
Stiffness of 1st Spring: 15 Newton per Millimeter --> 15000 Newton per Meter (Check conversion here)
Stiffness of 2nd Spring: 12 Newton per Millimeter --> 12000 Newton per Meter (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Keq = K1*K2/(K1+K2) --> 15000*12000/(15000+12000)
Evaluating ... ...
Keq = 6666.66666666667
STEP 3: Convert Result to Output's Unit
6666.66666666667 Newton per Meter -->6.66666666666667 Newton per Millimeter (Check conversion here)
FINAL ANSWER
6.66666666666667 6.666667 Newton per Millimeter <-- Equivalent Spring Stiffness
