Planning Scientific Knowledge: The seventeenth century scientist Robert Hooke was the first person to realize that the extension of a spring keeps in step with the force on it. So this result is now called Hooke's law. A simple way of describing this is by means of a graph. When the extension is directly proportional to the force, the graph is a straight line through the origin: The point at which a material ceases to obey Hooke's Law is known as its elastic limit. The first part is very easy. It means that the bigger the weight (stress) you hang on the string the more it will stretch (strain). The second part is also easy. Whilst the elastic limit is not exceeded, the string will go back to its original length when you take...
