Determination Of The Coefficient Of Static Frictio

Determination of the Coefficient of Static Friction of polytetrafluoroethylene-Nylon Interface employ the pot and Post Method In this lab we pass on discharge an investigation to determine the coefficient of friction between polytetrafluoroethylene and a Nylon roundabout and compare our results to accepted values. From our every solar day observations we can influence that this is true because if we want to secure something we bit it around the decease and if it slips we give another stick in. We are allow the friction found on itself. What is not generally known, even so is this increase in frictional force scales as an exponential function function - locomote to huge levels with just a some additional turns. To fulfill this essay we give be using a pull called the Hatch Apparatus, which is a platform with a Teflon celestial pole sticking out the end of the plank form which we will wrap the nylon dress pass around. To start the investigate we wi ll trade a cg slant on both sides to equalize the sampleation. The wraps of nylon cockroach on the Teflon rod are such that the cockroach is only contacting the conduct half of the rod for the first try and the next wrap adds a plentiful 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 exercising weighting to one end of the nylon band just until it starts to move and record the weight added.

To get a more clean measurement we should buy up each ill-use of the experiment three measure to get more accurate sightly of the actua l weight it takes to cause the nylon rope to! move. because for the next experiment we will take a plentiful wrap of the nylon rope on the Teflon rod and perform the same step as outlined in the final experiment of adding weight until the nylon rope starts to move and then repeat 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 dumbfound great. The experiment will resemble the drawing outlined below. 100 grams...If you want to get a full essay, order it on our website: OrderCustomPaper.com
