Springs in CombinationHardQuestion 31113

Question

Two springs (k₁ and k₂) in parallel. Effective spring constant:
  1. A
    k₁k₂/(k₁+k₂)
  2. B
    k₁ + k₂
    Correct
  3. C
    k₁ − k₂
  4. D
    k₁/k₂

Correct answer

k₁ + k₂

Explanation

For springs in parallel: k_eff = k₁ + k₂ (both stretch/compress by same amount, forces add).
