Hooke's law and the investigation of spring constant k

* Aim

To examine Hooke's law and to determine the value of spring constant k.

* Introduction

Robert Hooke (1635-1708) was born at Freshwater, Isle of Wight, son of John Hooke, curate at All Saints' Church [1]. He was one of the most brilliant and versatile of seventeenth-century English scientists, who discovered the law of elasticity. Between 1658 and 1678 Robert Hooke worked on his invention of the watch-spring and developed his theory of elasticity, now known as Hooke's law.[2] Hooke's law states that "the extension of a helical spring is directly proportional to the weight applied, provided the elastic limit of the spring is not exceeded." [3] However, the limitation of this law is if the spring is stretched beyond its elastic limit, meaning that there is a limit to a spring where if you stretch it too much it will deform, thus the spring will have a new spring constant.[4] Below is the equation of Hooke's law:

*where F = the force applied, here is the weight (N), k = the spring constant (N/m), e = the size
