What is the function of a spring-damper combination in control linkages?

• A. Spring stores energy and provides return force.
• B. Damper resists motion to prevent oscillations.
• C. Spring stores energy and provides return force; damper resists motion to prevent oscillations and provides smooth operation.
• D. Spring acts as a brake; damper cools the system.

Answer: (C)

In a spring-damper system used in control linkages, the spring stores energy and provides a restoring force to bring the mechanism back toward its rest position. The damper, on the other hand, resists motion, dissipating energy as the link moves, which slows movement and reduces velocity. This damping helps prevent oscillations and overshoot, leading to smoother, more controlled operation. Together, the spring handles energy storage and return, while the damper provides damping to smooth the response and avoid rapid, uncontrolled motion. The combination is essential for reliable, stable mechanical control.
