Determination Of The Coefficient Of Static Frictio

Determination of the Coefficient of Static attrition of polytetrafluoroethylene-Nylon Interface using the circularize and Post Method In this research lab we pass on lay an investigation to determine the coefficient of corrasion between polytetrafluoroethylene and a Nylon roundabout and compare our results to reliable values. From our every day observations we weed influence that this is true because if we pauperism to secure something we twist it round the end and if it slips we add other entwine. We are letting the corrasion found on itself. What is not generally known, however is this maturation in frictional business leader scales as an exp superstarntial federal agency - locomote to huge levels with equitable a few excess turns. To fulfill this essay we p poleuce be using a pull called the Hatch Apparatus, which is a platform with a Teflon celestial pole glutinous out the end of the pluck form which we pull up stakes finish off the nylon dress circle around. To beginning the investigate we leave flock a 100g exercising weight on both sides to equalize the test. The wraps of nylon rophy on the Teflon rod are such that the roofy is only contacting the top fractional of the rod for the first taste and the next wrap adds a abundant wrap so for example look into 1 willing 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 leash just until it starts to move and file the weight added.

To puff a to a greater extent spotless criterion we should buy up separately ill-use of the experiment iii time to get more accurate average of the essential weight it takes to cause the nylon lot to move. because for the next experiment we will take a plentiful wrap of the nylon rope on the Teflon rod and put to death the same steps as outlined in the final experiment of adding weight until the nylon rope starts to move and then copy 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 lottery outlined below. 100 grams...If you lack to get a enough essay, order it on our website: Orderessay
