- For a uniform spring, the product of the spring constant and the length is constant (kL = constant). - When the spring is cut into two equal halves, the length of each half is L/2. - Using the constant product relationship: k' (L/2) = k L - Solving for k': k' = (k L) / (L/2) = 2k.
A spring of spring constant k is cut into two equal halves. The spring constant of each half is now
