Springs - 1: Introduction

Define a Spring?

• A spring is an elastic object used to store mechanical energy

• Springs are elastic bodies (generally metal) that can be twisted, pulled, or stretched by some force.

• A spring is a flexible element used to exert a force or a torque and, at the same time, to store energy

• All the three

• Only 1 & 2

List the functions of springs?

_________is the cheapest spring steel used for low stresses and static loads.

Springs made of __________ steel is used for high stress conditions and at high temperature up to 2200 deg Celsius.

__________ spring material is most widely used for small springs. It is the toughest and has   highest tensile strength and can withstand repeated loading at high stresses.
