Design of Springs: Introduction and Applications

Strength and flexibility are the two essential requirements for spring design.

The major stresses produced in helical springs are shear stresses due to twisting. These stresses are produced when the load applied to the spring is parallel to or along the axis of the spring.

Three advantages of helical springs are: (a) they are easy to manufacture, (b) they are available in a wide range, and (c) their performance can be predicted more accurately.

<p>The characteristics of helical springs can be varied by changing their dimensions, such as wire diameter, coil diameter, and number of coils.</p> Signup and view all the answers

<p>The main applications of springs are: (a) to act as a reservoir of energy, (b) to absorb shocks and vibrations, (c) to return mechanical parts to their original position, and (d) to measure force.</p> Signup and view all the answers

<p>The two types of springs mentioned in the text are helical springs and conical/volute springs. Helical springs are primarily intended for compressive or tensile loads, while the loading capabilities of conical and volute springs are not explicitly discussed.</p> Signup and view all the answers
