WebFriction is determined by the two surfaces in contact, and how tightly the two surfaces are pushed together (normal force F_N F N ). Coefficient of friction ( \mu μ ): this describes … Webfriction, force that resists the sliding or rolling of one solid object over another. Frictional forces, such as the traction needed to walk without slipping, may be beneficial, but they …
WebMar 21, 2003 · A reasonable measure of slip-resistance is static coefficient of friction (COF). A COF of 0.5, which is based upon studies by the University of Michigan and reported in the "Work Surface Friction: Definitions, Laboratory and Field Measurements, and a Comprehensive Bibliography," is recommended as a guide to achieve proper slip resistance. WebMethod 4: Clamping. To measure the static coefficient of friction under conditions of high contact pressure the object may be clamped between two surfaces. The force necessary to put the object in motion must be halved to obtain the friction force because of the two contacting surfaces. Method 5: Pendulum.
