Rubber Band Investigation Essay Example

Elastic Band Investigation Paper I will examine the expansion of an elastic band, which I will submit to expanding Newtons of power being applied as 1N weights.PlanI will set the investigation up as follows:The elastic band will be connected to a counter stand, I will quantify the beginning size of the elastic band and afterward I will gauge it three separate occasions including 1N of power each time.I will proceed with this procedure until 10Ns where I will stop, to dodge Hookes law coming into place.To make it a reasonable test we are rehashing each degree of power included multiple times, trading the loads in the middle of each measurement.We will take a normal by including the 3 outcomes together and afterward partitioning by the aggregate sum of results. In the event that any outcomes which are peculiar or strange happen I will retake these outcomes to make a progressively exact generally result.We point find a consistent increment in the expansion of the elastic band, as expanding measures of power are applied .A key factor that should be controlled is how much the elastic band has been extended from one lot of 1-10 Newtons results to the following. Ideally this won't be an issue in light of the fact that the elastic band won't arrive at its constraint of elasticiticty until after 10 Newtons of power being applied.Extra InformationThe Law of versatility found by the English researcher Robert Hooke in 1660, which expresses that, for moderately little misshapenings of an item, the relocation or size of the disfigurement is straightforwardly relative to the twisting power or burden. Under these conditions the article comes back to its unique shape and endless supply of the load.Elastic conduct of solids as indicated by Hookes law can be clarified by the way that little relocations of their constituent particles, iotas, or particles from ordinary positions is additionally relative to the power that causes the displacement.The misshaping power might be applied to a strong by extending, compact ing, pressing, bowing, or turning. So an elastic band displays versatile conduct as indicated by Hookes law in light of the fact that the little increment in its length when extended by an applied power duplicates each time the power is doubled.Mathematically Hookes law expresses that the applied power F rises to a steady k times the removal or change long x, or F = kx. The estimation of k depends not just on the sort of versatile material viable yet in addition on its measurements and shape.At generally huge estimations of applied power, the twisting of the flexible material is regularly bigger than anticipated based on Hookes law, despite the fact that the material stays flexible and comes back to its unique shape and size after evacuation of the power. Hookes law depicts the flexible properties of materials just in the range in which the power and dislodging are relative. Some of the time Hookes law is detailed as F = - kx. In this articulation F no longer methods the applied pow er yet rather the equivalent and oppositely coordinated reestablishing power that makes versatile materials come back to their unique dimensions.No exacting security precautionary measures should be utilized just evident light safety measures are vital, as the main potential risk would be if the elastic band snapped, anyway this won't occur if there is close to the greatest burden on the spring of 10N at any one time.This will likewise evacuate the issue of the remain on which the test is occurring from falling over.1. Now the constraint of proportionality has been arrived at this is the place Hookes law is no longer accurate.2. This point is the elastic groups flexible cutoff if the power is expelled from the outlaw will no longer come back to its unique shape.Safety precautions* Be certain to keep your feet out of the zone wherein the majority will fall if the elastic band breaks!* Be certain to cinch the ring stand to the lab table, so the mass doesn't pull it off the table.* You have to balance enough mass as far as possible of the spring to get a quantifiable stretch, however a lot of power will for all time harm the band.** Hookes Law says that the stretch of a spring is legitimately corresponding to the applied power. state Stress is In images, F = kx, where F is the power, x is the stretch, and k is a consistent of proportionality. In the event that Hookes Law is right, at that point, the chart of power versus stretch will be a straight line.I will begin with the zero finish of the ruler even with the base of the elastic band when the spring scale is holding tight the elastic band. This will permit the adjustment long of the elastic band to be effectively determined.Apparatus I will use:1 counter stand3 elastic bands10*1 Newton weightsRulerMy input variable is power in Newtons applied and my yield variable is expansion of elastic band.PredictionI anticipate that after 10 N of power has been applied to the elastic band it will arrive at its versatile br eaking point and afterward it will begin to keep Hookes law, where the sum the elastic band is loosened up of shape past its unique size.I likewise foresee that the more noteworthy the weight applied to the band, the further the band will extend. This is on the grounds that expansion is relative to stack thus if load increments does as well augmentation thus extending distance.I additionally anticipate that the outcomes will deliver a straight-line diagram and if I somehow managed to proceed with the examination to additionally consider as far as possible I foresee the chart would straighten out after 11 Newtons were the elastic band would be loosened up of shape, or Hookes law would come into play.Extension = New length Original lengthto check whether my expectation is right I will test, and get results utilizing Hookes Law. He found that augmentation is relative to the descending power following up on the elastic band.Hookes LawF=kxF = Force in Newtonk= Rubber band steady proporti onalityx = Extension in CMMethod1. I set up the counter remain as appeared in chart 1 I put my jacket on the floor to ensure the tiles on account of the elastic band arriving at its versatile breaking point and snapping.2. I likewise secured the answer remain to the table with a brace rather than my unique arrangement of simply burdening the remain with my textbooks!3. I estimated the beginning length of the flexible band and afterward hung the band structure the hook of the answer stand , I at that point included expanding measures of power by including extra weights.4. I at that point estimated the expansion or augmentation of the elastic band from its unique size.5. I at that point evacuated the loads and set them back on and afterward recorded the outcomes to additionally times to get and average and an increasingly precise arrangement of results.6. I at that point rehashed this method for 2,3,4,5,6,7,8,9 and 10 Newtons of power and estimated the augmentation of the elastic band .7. I at that point chose to attempt to additionally examine Hookes law by really going past 10 Newtons of power to locate the flexible furthest reaches of the elastic band, (when the elastic band snaps!)8. I at that point arrived at the midpoint of out the entirety of my outcomes and produce a diagram, were I could see a line of best fit and demonstrate my forecast was right.ConclusionAfter doing this examination I was content with how it went, the down to earth was performed proficiently and we even had the opportunity to add and test to test the elastic groups flexible limit.I demonstrated the theory to be right and I likewise demonstrated my expectation was an exact forecast of what happened.I realized a ton about Hookes law and versatile cutoff points because of this examination and I feel it was a beneficial examination in helping me to comprehend about versatile limits.By breaking down my outcomes I have demonstrated my predication right that there will be an expansion in the length of the elastic band as you increment the measures of loads added.I was additionally totally right that the elastic band would have breaking point of flexibility at about 10N of power where it will be for all time in a bad way this expansion in elastic band size occurred as predicted.The thing that Surprised me about my conclusive outcomes was the way that the groups didn't snap until 13.5Newtons of power were applied, I anticipated the constraint of the groups to be in the locale of 10-12Newtons of power, not 13.5.To dissect these outcomes with my logical information I would need to state the increment long of elastic band is legitimately relative to the expansion in power applied so extending separation likewise increases.We altered are plan somewhat on the grounds that we had additional time toward the end we tried the restriction of versatility to attempt to demonstrate or negate Hookes law.By dissecting my charts with my logical information I can work out that the more p ower applied to the band, the more noteworthy the augmentation, that is the reason both my diagram get continuously taller as opposed to rising in the event that you needed to create a climbing chart you could begin with 10 Newtons of power applied and continue taking more loads off to bring down the extension.From my twofold elastic band test you can obviously observe there is less expansion all through in light of the fact that with two groups they can share the power applied in this manner with two groups there is a higher versatile cutoff then with only one elastic abnd.Overall I am satisfied with the result of this Investigation I accept that I have demonstrated Hookes law to be right and that after the restriction of versatility the elastic band is for all time put rusty.
