Aim To investigate the prototype in the amount by which a hanging piece of liveised offeres when a load big businessman is applied and the amount by which the stretch is reduced when the load is removed.Aim (in simpler terms) To determine the relationship between the force on a rubber band and its stretch, both during extension and retraction. venture Not required.Method1)Hang a piece of rubbery on a clamp stand. Ensure the expandable is new. 2)Clamp a rule using the clamp stand. Ensuring the markings on the ruler is as close to the compromising as possible. -Draw a diagram3) Measure the aloofness of the pliant and temper the data.4) Hang bandes on the elastic until it reaches it point of permanent distortion. Take note of this pitch do not hang more(prenominal) than this weight in the experiment.5)Add a weight of 100N (change trancely). carry for a few seconds for the system to stabilise. Measure the length of the elastic and record the data. Special care must be taken to ensure that when the mass is added the elastic should not retract.6)Add more weights, till the total weight is close to its point of irreversible distortion or till on that point are no more weights.7)Remove the weights one by one. Wait a couple of seconds for the system to stabilise. Measure the length of the elastic and record the data. Ensure that when the mass is removed the elastic should not be allowed to stretch further.8)Repeat, till there is no more mass on the elastic. Measure the length of the elastic.EquipmentElastic Clamp standRuler contrastive weights or a weight hangerVariablesIndependent Mass hung on elasticDependant continuance that the elastic extends or retracts.Controlled Same conditions thus the demeanor of the elastic is constant Same equipment ResultsForce (N)Length of elastic (m)Length that elastic was stretchedDuring extensionDuring retractionFor extensionFor retraction011.200.21001.51.40.50.4..........................................900....100 0....Note To find the length that the elastic was stretched. Simple subtract the value During extension by the original length of elastic. Then write the result in the mainstay For extension for the appropriate weight. Repeat for retraction.Construct a interpret of this data. For ease of data interpretation, graph force on y axis and length that elastic was stretched (that is the column For extension and For retraction) on x axis. Also possible to have intervals of 0.98 N on y axis so that value of mass in grams can be plotted accurately (assuming g=9.8 m/s2)Plot the points and draw a smooth curve.
