The spring material used in a spring control device should have the following property?
Correct answer: E. All of the above
- A. Should be non-magnetic
- B. Most be of low temperature co-efficient
- C. Should have low specific resistance
- D. Should not be subjected to fatigue
- E. All of the above
Explanation
Control springs should be non-magnetic, have a low temperature coefficient, and resist fatigue so their controlling torque remains stable. Low specific resistance is also traditionally specified for the spring material to reduce thermal effects, making all listed properties the intended answer.
