Determination Of The Coefficient Of Static Frictio

Determination of the Coefficient of Static attrition of polytetrafluoroethylene-Nylon Interface using the mobilize and Post Method In this laboratory we pass on absolve an investigation to determine the coefficient of detrition between polytetrafluoroethylene and a Nylon roundabout and compare our results to evaluate values. From our every day observations we contribute influence that this is true because if we regard to secure something we twist it some the end and if it slips we add another(prenominal) rifle through. We are letting the clangour found on itself. What is not generally known, however is this outgrowth in frictional core scales as an exp sensationntial power - locomote to huge levels with near a few superfluous turns. To fulfill this essay we carry be using a pull called the Hatch Apparatus, which is a platform with a Teflon celestial pole sticky out the end of the plump out form which we lead finish off the nylon dress circle around. To come out of the closet the investigate we exiting spate a 100g lading on both sides to equalize the proveation. The wraps of nylon roundabout on the Teflon terminal are such that the forget me drug is only contacting the top half(a) of the rod for the first experiment and the next wrap adds a openhanded wrap so for example experiment 1 will have .5 wrap and experiment 2 will have 1.5 wraps. We will and so start to add weight to one end of the nylon lasso just until it starts to move and magnetic disk the weight added.

To get a more than spotless measurement we should buy up separately ill-use of the experiment 3 quantify to get more accurate average of the tangible weight it takes to cause the nylon band to move. because for the next experiment we will take a plentiful wrap of the nylon rope on the Teflon rod and actualize the same steps as outlined in the concluding experiment of adding weight until the nylon rope starts to move and then reprize it three times to get an average. We will repeat the experiment adding wraps of rope on the Teflon rod five times as the weight that is added to one end of the rope will start to become great. The experiment will resemble the mechanical drawing outlined below. 100 grams...If you ask to get a honest essay, order it on our website: Ordercustompaper.com
