Hooke's law: hooke’s law, law of elasticity that relates the size of the deformation of an object to the deforming force or load. Another interesting thing about hooke’s law is that it is a a perfect example of the first law of thermodynamicsany spring when compressed or extended almost perfectly conserves the energy applied to it. Hooke's law hooke's law is a principle of physics that states that the force (f) needed to extend or compress a spring by some distance x is proportional to that distance that is: f = kx, where k is a constant factor characteristic of the spring: its stiffness, and x is small compared to the total possible deformation of the spring. Hooke's law is a relationship between restoring force and spring displacement or stretch discovered by robert hooke in 1660.

View lab report - hooke's law lab report analysis and conclusion from science ap physics at princeton high displacement in f=-kx, the spring constant that was determined was nearly identical, with. The results are definitely not totally accurate (as shown in the table), because the measurements were read off the meter stick by eye to the nearest mm. Hooke’s law experiment report done by yovaphine wijaya – 11 science 1 aim to investigate hooke’s law for simple strings or rubber hypothesis.

Phys-101 lab-03 elastic forces and hooke’s law 1 objective the objective of this lab is to show that the response of a spring when an external agent.
Talk:hooke's law this is the talk page for discussing improvements to the hooke's law you are trying to derive it from atomic-level analysis and have a. Hooke's law is a principle of physics that states that the force f needed to extend or compress a spring by some distance x is proportional to that distance that is, where k is a constant factor characteristic of the spring, its stiffness in other words, he discovered that elastic materials like coiled springs stretch proportionately with the. The following engineering design data, articles for mechanics / an analysis of hookes law strength of materials robert hooke frs (/ h k / 28 july [o.

Students are introduced to hooke's law as well as stress-strain relationships through the lesson's two-part associated activity, students 1) explore hooke's law by experimentally determining an unknown spring constant, and then 2) apply what they've learned to create a strain graph depicting a tumor using microsoft excel. Generalized hooke's law stress-strain calculator is used to calculate stress-strain relations of a homogeneous isotropic material under most general stress/strain conditions if strains on a structure are measured in elastic range, stresses can be calculated from these results with the usage of hooke's law strain - stress calculator. A basic understanding of the concepts of hooke's law, stress and strain, as presented in lesson 2 learning objectives after this activity, students should be able to: describe what is meant by hooke's law apply hooke's law relationships to analyzing tissue of a known surface area. Referred to as the “static method,” which utilizes hooke’s law, given in equation (1) the second method, the “dynamic method”, makes use of the fact that the system exhibits simple harmonic motion thus, you are able to perform two independent experiments to extract a property of spring – it’s spring constant.
Abstract hooke's law says that the opposing force of a spring is directly proportional to the amount by which the spring is stretched how accurately hooke's law describe the behavior of real springs. Alaa khoja , id: 25881612 hooke’s law and material’s behavior abstract: in this experiment of hooke’s law, the behavior of three different materials was monitored each materiel was subject of different forces by hanging on it different masses ,the resulting values of the extension of the first material were (3mm at first and then.
Hooke’s law experiment objective: to measure the spring constant of a spring using two different methods background: if a weight, w = mg, is hung from one end of an ordinary spring, causing it to stretch a distance x, then an equal and opposite force, f, is created in the spring which opposes the pull of the weight if w is not so large as to. John p hussman, phd though i continue to view stocks as reasonably undervalued, i'm a bit concerned that so many investors appear to be looking for a bottom the s&p 500 currently reflects the best valuations since the 1990 bear market low even in the event of a continued bear market, stocks are. Data analysis using graphs written by zikri yusof numerous times during the introductory physics laboratory courses, you will be asked to graph your data as part of your analysis. Hooke’s law hooke’s law is a scientific law which concerns itself with the elasticity of materials it states that when a force is applied to a spring, the displacement of that spring will be directly proportional to the amount of force applied. Elastic forces and hooke’s law 1 objective the objective of this lab is to show that the response of a spring when an external agent analysis 1 plot a graph. Hooke’s law in terms of stress and strain is stress strain in terms of the definitions l l y a f the constant of proportionality is called the elastic modulus or young’s modulus if.
Utc physics 1030l: spring constant 66 the spring constant objective: to determine the spring constant of a spiral spring by hooke’s law and by its period of oscillatory motion in response to a weight apparatus: a spiral spring, a set of weights, a weight hanger, a balance, a stop watch, and a two- meter stick theory. 20a-hooke's law - 2 - revised: 4/17/07 the variable x represents the magnitude of the distortion or displacement from equilibrium as exhibited in the stretching of a spring or rubber band the factor k is the proportionality. A critical analysis of stress theory in material science hooke's law states that the elongation (strain) of elastic materials is proportional to the applied force.
