1. The problem statement, all variables and given/known data Suppose you have 2 springs in series, one is linear and one is non-linear. Initially the linear spring is at the top position and the non-linear is on bottom. Does swapping the springs affect the system? 2. Relevant equations 1/k_eq = 1/k1 + 1/k2 This equation doesn't apply though since we have a non-linear spring. x_tot = x1 + x2 3. The attempt at a solution I would say that it does not affect the system because x_tot in both cases will be equal, hence, F will be equal. x_tot = x1 + x2 = x2 + x1 Is this correct?
