1. The problem statement, all variables and given/known data An automobile can be considered to be mounted on four identical springs as far as vertical oscillations are concerned. The springs of a certain car are adjusted so that the oscillations have a frequency of 3 Hz. (a) What is the spring constant of each spring if the mass of the car is 1300 kg and the weight is evenly distributed over the springs? 2. Relevant equations w = (k/m)^(1/2) k(total) = k1 + k2 + k3 + k4 = 4k 3. The attempt at a solution Since the springs are arranged in a parallel fashion, I can add their individual spring constants for an overall constant. Since the springs are identical, I can rewrite the sum of constants as 4k. Then, using the first equation listed above I have: 3 = (4k/1300)^(1/2) and solving for k I found the solution to be 2925 N/m. What's wrong with my approach?
