1. The problem statement, all variables and given/known data Consider a mass attached to four identical springs, as shown in the figure. Each spring has a force constant k and an unstretched length lo, and the length of each spring when the mass is at equilibrium at the origin is a (not necessarily the same as lo). When the mass is displaced by a small distance, show that its potential energy has the form (1/2)kor2 appropriate to an isotropic harmonic oscillator. Express the constant ko in terms of k. 2. Relevant equations 3. The attempt at a solution I just need help with interpreting this. The question didn't specify, it only told me they were different.
