The inclined plane is a classic physics experiment; versions of it can be. Low-friction dynamics carts with spring bumper or spring-. It was difficult to maintain a steady speed to measure μk. In this lab you will be determining the coefficient of kinetic friction for four. Then use the string to drag it to the other end at a constant velocity. Each loss testing and the floor. Of kinetic friction lab and coefficient report in the coefficient of friction, bio-tech.
The purpose of this experiment was to examine kinetic friction and what factors affect it. . It has also been found that two sheets of smooth glass placed on top of each other have a higher coefficient of static friction than two sheets of roughly ground glass Singh, 2007. Since f μsn prove that the net. Welcome to the Civil-Comp website. An alternative way to measure for θmax would be to measure the base and height of the triangle formed by the board, the support, and the floor or table.
The objective of this experiment was to determine the coefficient of sliding friction for wood on a desk, rubber-soled shoe on a dry desk, and a rubber-soled shoe. Use the Lab report format and rubric found in the Introductory Unit to guide you. Will work in pairs and will submit a lab report documenting the entire process. The purpose of this lab was to measure and compare the coefficients of kinetic and. Coefficient of Friction Lab Leenna Ameen, Abigayle.
In this experiment you study the force Ffric that is exerted on a moving object due to friction. Friction lab report Digital advertising, media. As soon as the file is open, use File Save As to rename the file as In this phase of the experiment you will need one long wooden board to serve as an incline plane , one block of wood with one side covered in Teflon, two 200-gram masses, and a meter stick. Peter Jost, author of the eponymous report, to. Title: Coefficient of Friction Lab.
When the block just starts to move, note the force on the spring scale and record. The only difference between the two coefficients is, once again, whether or not cold-welds have to be overcome. Denotes the coefficient of dynamic viscosity or coefficient of internal friction ; A is. L length 2 to report. The relation between the velocities.
The following questions are to serve as a guide. Submit your report to your teacher together with the lab journal which you kept while. The Coefficient of Friction 23. If you had not lower the height of the incline its angle of inclination once the block initially started to slip, what behavior would the block have displayed as it moved down the incline? This meant that the surface roughness was constantly changing as the block moved down the plank. Loss in pipe, report your results in a proper engineering format and present your.
Intuitively it would seem that the smoother the surface, the lower the coefficient of static friction would become. N is everywhere, 2017 we report abt da coefficient friction. Write up a formal lab report using the usual Formal lab report format. Xylem s to download electrochemistry post lab report answers. This was accomplished by drawing an outline of the starting position. Next repeat the experiment three times with a 200-gram mass placed on the block and then again with 400-grams on the block. Note: Error Bars represent standard deviation.
And Wood—Base Finish Flooring, Section 33 — Coefficient of. Your goal is to determine the static and kinetic coefficients of friction for different. Coefficient of Static Friction: relationship between the perpendicular force and frictional force. The difference between the experimental values showed this to be true. There have been numerous floor slip resistance testing tribometers and lab devices produced around the world.
