Introduction
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:
*
Middle
This is a specific form of Hooke’s law ofelasticity.
- Method
The equipments needed in the experiment are a spring; a number of weights which each of them is 100gram heavy; a meter ruler; a ring stand; clamps; notebook and pencil. They were placed as shown in the diagram.
To begin the investigation, the spring was attached to the ring stand. Next, two of the 100-gram loads were hung under the spring and the ruler was used to measure the extension of this spring. Subsequently, 2 more loads were added and the process of measurement was repeated. The number of loads was continuously increased until the total mass reached 1 kg. Between each
