The figure shows the stable condition of the spring when no load is applied, the condition of the spring when elongated to an amount x under the load of 1 N, the condition of the spring elongated to … Hooke's Law was first determined by Robert Hooke in the 17th century. To conclude, the experiment proves Hooke’s law. The experiment on the Hooke’s Law will help to determine the behaviour of three different elastic materials, and help to investigate the differences of their behaviour around their elastic regions. Hooke's law states that when an elastic material is subjected to a force, its extension (x) Hooke's law is a law of physics that states that the force (F) needed to extend or compress a spring by some distance (x) scales linearly with respect to that distance—that is, =, where k is a constant factor characteristic of the spring (i.e., its stiffness), and x is small compared to the total possible deformation of the spring. Experiment. When masses are applied to materials Y 1 and Y 2 , they stretch within their elastic limit showing that the force applied is directly proportional to the extension of the material. Hooke’s Law Experiment Consider a spring with load application as shown in the figure. Once a sufficient amount of force has been applied, so as to extend the material beyond it’s elastic limit, the material enters it’s plastic region. With the material in it’s plastic region, the force applied causes permanent displacement of … Hooke’s law, law of elasticity discovered by the English scientist Robert Hooke in 1660, which states that, for relatively small deformations of an object, the displacement or size of the deformation is directly proportional to the deforming force or load. 2. I put ruler from the bottom of the loop on the spring across to a metre stick behind. I did this because I needed to be sure that although the spring wasn't touching the metre stick, I had the spring and the metre stick lined up properly. EXPERIMENT 4 HOOKE’S LAW 1. Investigating Hooke’s Law. Aim.

The force can easily be calculated by hanging it at the end of an attached string then, using the equation weight = mass x gravity (F = mg). 2. Hooke's Law says that the stretch of a spring is directly proportional to the applied force. A formal lab report should include a title page like this one, with all of the appropriate information -- a descriptive title, your name, the course title, the date, and an abstract. Where F is the force applied to the spring, k is the spring constant, and x is the extension of the spring. In symbols, F = kx, where F is the force, x is the stretch, and k is a constant of proportionality. Material z however, does not follow Hooke’s law. Hypothesis The change in length of spring is directly proportional to the applied so that it will cause greater change in … This experiment is aimed to investigate the relationship between the mass that is being slotted at the end of spring and the time taken for … Hooke’s Law Experiment Report Done by Yovaphine Wijaya – 11 Science 1 Aim To investigate Hooke’s law for simple strings or rubber. If Hooke's Law is correct, then, the … Equipment Tripod Base Barrel Base Support Rod, square, l=1000mm Right Angle Clamp Cursor, 1 pair Weight Holder f. Slotted Weights Slotted Weight, 10g, black behavior follows Hooke's law to within the limits of accuracy of the experiment. Under these conditions the object returns to its original shape and size upon removal of the load.

Hooke’s law applies, as long as the material is within it’s elastic limit. Objectives The main objective of this experiment is to show Hooke’s Law of spring, calculate the total energy absorbing in the spring. (Engineers say "Stress is proportional to strain".)
