3. WHAT IS SPRING? Springs are e lastic bodies (generally metal) that can be twisted, pulled, or stretched by some force. They can return to their original shape when the force is released. In other words it is also termed as a resilient member.

4. CLASSIFICATION OF SPRINGS Helical springs 2 ) Leaf springs

5. HELICAL SPRING CLASSIFICATION Extension helical spring Compression helical spring Torsion spring Spiral spring

6. What is helical spring Helical spring is a spiral wound wire with a constant coil diameter and uniform pitch

7. Function of Helical spring Used to store energy and subsequently release it To absorb shock To maintain a force between contacting surfaces

8. EXTENSION HELICAL SPRING It has some means of transferring the load from the support to the body by means of some arrangement. It stretches apart to create load. The gap between the successive coils is small .

9. EXTENSION HELICAL SPRING The wire is coiled in a sequence that the turn is at right angles to the axis of the spring. The spring is loaded along the axis. By applying load the spring elongates in action

10. EXTENSION SPRINGS AND ITS END HOOKS

11. COMPRESSION HELICAL SPRING Among the four types, the plain end type is less expensive to manufacture. It tends to bow sideways when applying a compressive load .

12. TORSION SPRING It is also a form of helical spring, but it rotates about an axis to create load. The ends of the spring are attached to other application objects, so that if the object rotates around the center of the spring, it tends to push the spring to retrieve its normal position.

13. FUNCTIONS OF TORSION SPRING It releases the load in an arc around the axis. Mainly used for torque transmission

14. SPIRAL SPRING It is made of a band of steel wrapped around itself a number of times to create a geometric shape. Its inner end is attached to an arbor and outer end is attached to a retaining drum .

15. FUNCTIONS OF SPIRAL SPRINGS It has a few rotations and also contains a thicker band of steel. It releases power when it unwinds.

16. LEAF SPRING Sometimes it is also called as a semi-elliptical spring, as it takes the form of a slender arc shaped length of spring steel of rectangular cross section. The center of the arc provides the location for the axle,while the tie holes are provided at either end for attaching to the vehicle body.

17. FUNCTIONS OF LEAF SPRINGS Heavy vehicles leaves are stacked one upon the other to ensure rigidity and strenth . It provides dampness and springing function.

18. Spring testing machine

19. APPLICATIONS OF SPRINGS To apply forces and controlling motion, as in brakes and clutches. Measuring forces, as in the case of a spring balance. Storing energy, as in the case of springs used in watches and toys. Reducing the effect of shocks and vibrations in vehicles and machine foundations .

22. Torsional compression springs are used when you need a torsion spring to also complete the task of compressing or providing some sort of suspension against the objects around it while completing the task of exerting a radial force as well.

23. Elastic Potential Energy

24. Hooke’s Law The stretch or compression of an elastic device (e.g. a spring) is directly proportional to the applied force

25. CONCLUSION Springs produce a large deflection and used for a number of applications. Most springs are made of steel. Stress and deflection in coil springs was derived. Springs can be connected in series and parallel. There are a number of other spring configurations used in engineering.
