Q) What is the function of an extension spring?
A) To provide extended force when the spring is pulled apart from its original length.
Q) How do extension springs absorb and store energy?
A) By offering resistance to a pulling force. Various types of ends are used to attach the extension spring to the source of the force.
Q) Concerning extension springs, where do most failures occur?
A) Most extension spring failures occur in the area of the end. To maximize the life of the spring,the path of the wire should be smooth and gradual as it flows into the end.
Q) What needs to happen for an extension spring to have no initial tension?
A) The Extension Spring needs to be designed with space between the coils.
