If i you measured the keffective of the two springs acting together. if the two springs had k1 and k2 individually.
a. Their keff in series is 1/keff = 1/k₁+ 1/k₂
b. Their keff ins paralle is keff = k₁+ k₂
If i you measured the keffective of the two springs acting together. if the two springs had k1 and k2 individually, to find how would they combine to get keff, we proceed as follows
There are two ways of combining spring namely in series and in parallel.
a. Springs in series
Since we have the springs k₁ and k₂ in series, their effective spring constant keff is
1/keff = 1/k₁+ 1/k₂
b. Springs in parallel
Since we have the springs k₁ and k₂ in series, their effective spring constant keff is
keff = k₁+ k₂
