Coefficient Of Friction

Coefficient of Friction By Omar Ramadan Partners: Samuel Saarinen Brian Urbancic Feb 23, 2012 Abstract: The coefficient of clash is a specify along that determines how lots push back is required to move an purpose that is held back by clangour. The goal of our experiment was to measure the motionless and kinetic slue coefficient of friction between ii surfaces by using a kurrat and measuring its inclination. The premise is that when a solid intention is placed on a ramp and the ramp is flex upward, there is a point that the object starts to slide. That is the tap where the force of gravitational force is strong comme il faut to overcome the kinetic and silent friction. Once the angle, or the inclination, is known, we stool so calculate the skid coefficient of friction between the two surfaces. Experimental Description: In this experiment, to determine the coefficients of friction, both placid and kinetic, our dredge with an aluminum underside was allowed to slide down an disposed(p) up tack. Several choices of covering for the inclined plane were inclined including aluminum, polyethylene, or left as scanty wood. We raised the plane to an angle such that the cart would somewhat start moving, then we measured the angle of the plane by using protractor and the sonic ranger to determine the acceleration of the cart (the calibration of sonic ranger 0.012 percent error).

This procedure was performed iii times, each with a different inclined plane. Data and depth psychology: The coefficient of placid friction was derived in the following manner: Coefficient of static friction = (force o! f friction) / (normal force) Force of friction = horizontal instalment of solemnity = m * g * sin ? Force = vertical component of gravity = m * g * romaine lettuce ? Coefficient of static friction = m*g*sin ?/ (m * g * cos ?) = convert ? Coefficient for kinetic friction = [g*m*sin ?-(a/m)]/ [g*m* cos ?] Where ? is the angle of the incline surface. We calculated the coefficients for each combination, using the...If you loss to get a full essay, order it on our website: OrderCustomPaper.com
