Unformatted text preview: Summary Lecture Summary Lecture 8 Static Friction: Up to a maximum the static friction force is to maximum the static friction force is equal to the applied force. The maximum static friction force is: FFr(max) = μs FN Kinetic Friction: The kinetic friction force is: kinetic friction force is: FFr = μk FN μk < μs FFriction For the same set of materials the coefficient of static friction is larger than the one for kinetic friction Kinetic Fapplied Objects on an inclined surface Y: FN – mg cosΘ = 0 X: F – FFR – mg sinΘ = ma +y FN +x Choose your your coordinate system wisely!
