Worked practice questions

Two springs of constants $k_1$ and $k_2$ connected in **series** have effective spring constant:

  1. $k_1 + k_2$
  2. $k_1 k_2 / (k_1 + k_2)$
  3. $k_1 - k_2$
  4. $\sqrt{k_1 k_2}$
Show answer and solution

Correct answer: B. $k_1 k_2 / (k_1 + k_2)$

**Series:** $1/k_{eff} = 1/k_1 + 1/k_2$ ⇒ $k_{eff} = k_1 k_2/(k_1+k_2)$. (Series springs both stretch under same force, so total extension adds up — like resistors in parallel.) Parallel springs (both stretch the same amount) give $k_{eff} = k_1 + k_2$.
