Experiment. To verify Hooke's law - Hooke's law states that the extent to which an elastic material will change size and shape under stress is directly proportional to the amount of stress applied to it.. Conducted experiment proved that according to Hooke’s Law deformation of the material is linear until certain amount of force is reached and once that limit is reached Hooke’s Law stops applying. As the stretch increases, the force increases, and it is a constant increase. For the first spring, the results obtained are not very accurate due to the sources of errors identified above. The two materials behaved in accordance with Hooke’s Law, extending proportionally to the force applied to them. Results obtained from the Hooke’s Law experiment. Figure 3: Graph of Deformation for material Y 1, and Y 2 against Force Applied, X.. Table 1 shows the result obtained from the Hooke’s Law Experiment of the 3 different elastic materials (Y 1, Y 2 and Z). Hooke’s law of elasticity states that the size of a material’s deformation due to a tensile load, is proportional to the force applied that is acting to deform the material [1][4]. Also, the proportional limit is the maximum stress for which stress and strain are proportional. Experimental conclusions and evaluation. Hooke's Law, also known as the law of elasticity, states that there is a direct correlation between the Force applied to an object and the amount it… If W is not so large as to permanently distort … In this region, labelled on the graph as the Hooke's law region, F=kx, as expected. The starting position of the spring was recorded using a stretch indicator. This shows that the extension is proportional to the force applied to the spring. This leads to the conclusion that the experiment was conducted successfully as it has been proven that the Hooke’s Law can be applied in this experiment. This relationship was described in an equation that Hooke used. They are both elastic objects. However, the deformation and force in spring 3 were not linearly correlated as it was no longer obeying Hooke’s Law. Hooke's Law Experiment. In other words force is proportional to the extension of stretched material. K is the spring constant and is … The most popular law of elasticity is Hooke’s law. the spring constant, force (N), and displacement/position of spring (m). Add additional 50 gram masses to the mass holder and record the position of In conclusion, Robert Hooke was a dominant scientific leader of the 17th century, who contributed to all aspects of science. This law has been applied in making a balanced spring that was used in portable time pieces. Let's take down to be the positive direction so that the force exerted on the hanging mass can be written as F x = -k(x-x o This was repeated with various amounts of mass. Introduction: hooke’s law . Translate PDF. F = kx F is the force applied to the… It was also found that k1 > k2 meaning spring 1 was stiffer than spring 2. Experiment 1. References; 1. Aim. Hooke's Law . In this experiment Hooke's law was proven because the graph of the recorded data proved to be linear with the exception of a few points in the beginning. In conclusion, it could be said that the experiment is successful in verifying value of the spring constant. It will eventually fail once the material undergoes compression or tension beyond its certain elastic limit without some permanent deformation or change of state. Conclusion. When masses are applied to materials Y1 and Y2 , they stretch within their elastic limit showing that the force applied is directly proportional to the extension of the material. The linear correlation coefficient is strong and positive the closer to 1 it is. the experiment is conducted to investigate the behaviors of three materials which is y1 , y2 and z. hooke’s law states that the force that is required to stretch or … A change in length ∆ l is formed. Fig.5: Graph of Hooke’s Law Experiment Material 3 . To determine the Newtons from grams is to take the amount of grams and multiplying it by force of gravity which is 9.8g and then dividing it by a thousand to determine the unit conversion for Newtons. Attach a 50 gram (0.050 kg) mass holder to the spring and measure the new position s1 to which the reference point on the spring is extended. The correlation can be expressed linearly and can be demonstrated with the use of graphs as shown below (Figure 1): Figure 1. To conclude, the experiment proves Hooke’s law. Physics 161. According to Robert Hooke, an English scientist of the 17th century, for a range of values, the magnitude of an object's deformation is directly proportional to the force applied to it. Medicine practitioners used titanium plates to withstand the stress of our body's weight because it has the ability to do so. conclusion. Conclusion: In this experiment, the stretch of a spring changes as the force applied on the spring changes. As a child he was a quick learner who was interested in many fields e.g. CONCLUSION: From the experiment performed above, it can be concluded that the Hooke’s law holds true for a metal spring. 4. ). Robert Hooke (shown in the picture below), who is well known for creating the “Hooke’s Law”, was born in 1635 in Freshwater on England’s Isle of Wight. This whole lab can be done from the “Intro” page, so click that. The two materials behaved in accordance with Hooke’s Law, extending proportionally to the force applied to them. – (negative sign) is showing the direction of the reaction force opposing the external force. Hooke's Law Lab Report. 9. Theory. This is because the extension produced by the spring is directly proportional to the force applied on it. The change in length of spring is directly proportional to the applied so that it will cause greater change in length of the spring for greater force applied. Objective. I also calculated the average of trial 1 and 2 as the data for conclusion graph. We also needed to regulate whether or not the spring obeys Hooke's Law, and it found true here. Introduction to Robert Hooke and Hooke’s Law Portrait of the famous Renaissance scientist Robert Hooke. Position for our hooke's law experiment, along with the best fit line. My suggestion to improve the experiment is to carefully measure the extension of the spring despite the variation of the spring. Conclusion. Conclusion of simple pendulum experiment? According to Hooke's Law, a spring should be as long as x from its normal length. In Figure 3., Graphs 1 and 2 are linear as expected. Table 1: Result of the 3 different material obtained from the Hooke’s Law Experiment. Hooke's law states that when an elastic material is subjected to a force, its extension (x) According to Hooke’s Law¹²³, the namesake of which comes from the scientist who first defined the principle in 1660 – Robert Hooke, there is Measure the position of the end of the spring after the table has been attached. in this blog , i will be writing about the result and conclusion of the investigation from the hooke’s law experiment . Done by Yovaphine Wijaya – 11 Science 1. Hooke’s law discussed earlier, with G= kT. Hooke’s law also referred to as the law of elasticity was discovered by an English scientist named Robert Hooke in the year 1660. So, that means that if you apply … Hooke’s Law is a theory of classical mechanical physics by Robert Hooke.It states that the force (F) needed to extend or compress a spring by a distance (X) is proportional to that distance. Hooke’s law experiment discussion and conclusion Limitation of Hooke’s law: Hooke’s law is a first-order approximation to the response of the elastic bodies. Section #1 Abstract: The aim of this laboratory experiment is to calculate a spring constant k for different spring expressions using Hook’s law. We set out to find the spring constant and see if it obeyed Hooke's Law. Hooke S Law Experiment Assyrian Border Style 3 Ashur. This is true solid metals but not polymers, providing the force acting on the material does not cause a deformation beyond its elastic limit [2]. Position and select the Force Curve run. By using F = kx the gradient of my line on the graphs being the object k and the x being the extension measured you can see that if K= 0.025 (single spring gradient) X = 71mm (2n) F= 1.78 Conclusion. F=Kx when K is a constant factor of the…show more content… In the following blog post, I will investigate the results that I have got when carrying out Hooke's Law experiment. Hooke's Law was developed by Robert Hooke in 1660 and this law pertains to elasticity. Hooke`s Law Rustem Kushtayev .Physics 161. Experiment. The elastic limit is the stress beyond which irreversible deformation occurs. In symbols, F = kx, where F is the force, x is the stretch, and k is a constant of proportionality. Besides, my results show the same as Hooke’s Law. Hooke's law states that for an elastic spring, the force and displacement are proportional to each other. It means that as the spring force increases, the displacement increases, too. If you graphed this relationship, you would discover that the graph is a straight line. References Hooke’s Law. Hooke’s Law states that when an elastic object (spring) is stretched,the increased length is called extension .The force applied to an object is directly proportional to the extension produced up until elastic limit . It will eventually fail once the material undergoes compression or tension beyond its certain elastic limit without some permanent deformation or change of state. The spring constant is 2.3 N/m. Attach a 50 gram (0.050 kg) mass holder to the spring and measure the new position s1 to which the reference point on the spring is extended. Spring y1 is ‘stiffer’ than y2 as spring y1 has a higher spring constant than that of y2. The applications of Hooke's Law are as follows:Hooke's Law is used at all branches of science and engineering; For understanding the behaviour of elastic materials there is no substitute of Hooke's law.It is used as the fundamental principle behind the manometer, the balance wheel of the clock, and a spring scale.Foundation for seismology, molecular mechanics, and acoustics. Hooke’s Law. The constant 'k' (called the … Hooke’s law basically states that “when an object has a relatively small deformation the size of the deformation is directly proportional to the deforming load or force.”. Experiment 10 The Spring: Hooke’s Law and Oscillations 10.1 Objectives • Investigate how a spring behaves when it is stretched under the in u-ence of an external force. Record the slow 7 cm compression (as in step 2 on previous page.)
