1. The problem statement, all variables and given/known data A spring with spring constant 8 N m-1 is cut into 2 equal parts. Find the spring constant of each part? 2. Relevant equations 3. The attempt at a solution Spring constant of each part = 16 N m-1 Above is the answer given. 1. Why should we times 2? 2. If the spring is cut into a ratio of 1:2:3, then what should be the spring constant of each parts?
