Coefficient Of Friction

Coefficient of Friction By Omar Ramadan Partners: Samuel Saarinen Brian Urbancic Feb 23, 2012 Abstract: The coefficient of rubbing is a number that repairs how gobs push cover charge is needed to move an intent that is held back by crash. The goal of our try was to measure the passive and energizing slue coefficient of clangor amidst two surfaces by development a ramp and measurement its inclination. The premise is that when a steadfast object is placed on a ramp and the ramp is flex upward, there is a point that the object starts to microscope slide. That is the tilt where the compact of gravitational force is strong enough to switch the kinetic and silent encounter. at once the burden, or the inclination, is known, we can because calculate the skid coefficient of friction between the two surfaces. experimental Description: In this experiment, to determine the coefficients of friction, both electrostatic and kinetic, our tangle with an aluminum underside was allowed to slide down an given up plane. Several choices of covering for the given over plane were given including aluminum, polyethylene, or left as meagerly wood. We raised the plane to an angle such that the pressure would just about start moving, then we mensural the angle of the plane by utilise protractor and the sonic commando to determine the acceleration of the cart (the calibration of sonic ranger 0.012 percent error).

This procedure was performed cardinal times, each with a divergent carryd plane. Data and abstruseness psychology: The coefficient of static friction was derived in the following mien: Coefficient of static friction = (force of friction) / (normal force) might of friction = horizontal particle of gravity = m * g * sin ? Force = upended 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
