What is the length of a compression spring when the deflection reaches a maximum?
a. Solid length
b. Free length
c. Pitch
d. None of the above

Solution

Solid Length (H)
Length of a compression spring when under sufficient load to bring all coils into contact with adjacent coils; no additional deflection is possible.

Pitch (p)
The distance from center to center of the wire in adjacent active coils(recommended practice is to specify number of active coils rather than pitch).

Free length (L)
The overall length of a spring which is not under load.

Hence The answer ia D. (none
