Students explore hooke's law while working in small groups at their lab benches others may emphasize the testing and analysis phases hands-on activity: applying hooke's law to cancer detection contributed by: vu bioengineering ret program, school of engineering, vanderbilt university. 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. Hooke's law and simple harmonic motion however, when applying this spring constant to the recorded displacements in the hooke's law equation, the calculated forces are lower than the recorded forces in similar manner. 1 hooke's law and a simple spring donald c peckham physics 307 fall 1983 (digitized and revised, fall 2005) abstract the spring constant of a screen-door spring was determined both statically, by.
If hooke's law holds for the spring and the data fits a straight line, then the motion of masses vibrating up and down on the spring should be simple harmonic motion example excel spreadsheet for analysis of simple harmonic motion of a. 1 experiment: the spring i hooke's law and oscillations objectives: to investigate how a spring behaves if it is stretched under the influence of an external force. Primary sidebar widget area email subscription enter your email address: delivered by feedburner regents exam countdown. Rods: axial loading and deformation - if the resultant axial stress = p/a dos not exceed the proportional limit of the material, then hooke's law can applied, that is - analysis of internal forces 75 kips 45 kips 30 kips 1 2 3.
Hooke's law will be verified for a spring and the force constant will be calculated by measuring the amount the spring is stretched when various masses are hung on it example excel spreadsheet for analysis of simple harmonic motion of a. Hooke's law and simple harmonic motion hooke's law elastic force occurs in the spring when the spring is being stretched/compressed or deformed. This question was answered by robert hooke, a contemporary and rival of isaac newton hooke's law, believe it or not modern computer software takes just about all of the drudgery out of data analysis. Study guides get your head around tough topics at a-level with our teacher written guides learn more. 3d stress and deflection using fea analysis tool 3d fea stress analysis tool : in addition to the hooke's law, complex stresses can be determined using the theory of elasticity. 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 in the hooke's law experiment, you are given that for a spring still within its.
Static springs: hooke's law printer friendly version: purpose the purpose of this lab is to use linear regression and data analysis to calculate the elasticity constant for a single spring, and for springs arranged in series and in parallel. 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 of mass added, m (y-axis) vs spring extension, l for the data of table-i.
Hookes law- to determine the spring constant of a metal spring hypothesis the independent variable of this experiment is mass (the number of masses added) and the dependent variable is extension (the extension of the spring) the control variables. Hooke's law physics calculator solving for force given spring force constant, distance from equilibrium, and spring equilibrium position. Physics report hooke's law - free download as word doc (doc / docx), pdf file (pdf), text file (txt) or read online for free. Stress-strain material laws 5-1 lecture5:stress-strainmateriallaws table of contents page hooke's law, originally enunciated by robert hooke by 1660 for a spring, and later expressed in terms of stresses and strains once those concepts appeared in the xix century. Guidelines for a physics lab reports the analysis of the experimental data a few neatly written pages hooke's law experiment objective: to measure the spring constant of a spring using two different methods background.
Hooke's law is the statement that the restoring force acting on an object is proportional to the negative of the displacement analysis convert all masses to newtons and all meter stick readings to meters plot all the data on the graph paper. Hi can anyone suggest a way to take an analysis of a hookes law experiment at alavel up to the next step at low loads there is a reduced amount of extension - can anyone suggest why is this due to intial tensioning of teh spring in question. I abstract the experiment is purely on hooke's law and the concept of elasticity it is performed simply by putting weights on the mass hanger using hook. 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. Home strength of materials analysis of strains and hooke's law analysis of strains and hooke's law posted by : analysis of strains concept of strain concept of strain : if a bar is subjected to a direct load, and hence a stress the bar will change in length.
