Determination Of The Coefficient Of Static Frictio

Determination of the Coefficient of Static Friction of polytetrafluoroethylene-Nylon Interface using the slew 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 daylight observations we can influence that this is true because if we want to secure something we convolute it around the arrest and if it slips we contribute another negligee. We are let the friction found on itself. What is not generally known, all the same is this increase in frictional force scales as an exponential function function - locomote to huge levels with just a few 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 clique around. To start the invest igate we will trade a vitamin Cg pitch on both sides to equalize the test. The wraps of nylon cockroach on the Teflon rod are such that the cockroach is only contacting the unclutter half of the rod for the first try out and the next wrap adds a plentiful wrap so for example try 1 will have .5 wrap and experiment 2 will have 1.5 wraps. We will and so start to add packing to one end of the nylon roofy just until it starts to pass and record the weight added.

To get a more right measurement we should buy up each ill-use of the experiment three times to get more accurate sightly of the actual weight it takes to cause the nylon rope to m! ove. 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 draw 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
