Matlab code

Problem: 100g masses (equivalent to a weight or a force of 1 newton) hang on the spring and measure its extension as each 100g mass is added, then plot of the extension against the load or the force (in newtons), as shown in the graph From the graph can be seen that it is a straight line through the origin Which means that the force applied to the spring and the extension of the spring are directly proportional. Mathematically can be write: Force = constant x extension And the "constant" is known as the "spring constant" Force = spring constant extension F=ke where F is force in newtons, N k is the spring constant in newtons per metre, N/m and e is the extension in metres, m
