Coefficient of static friction si unit
WebAn object of mass 1.7 kg is at rest on a rough horizontal surface. The coefficients of static and kinetic friction are 0.74 and 0.51 respectively. Calculate the magnitude of the maximum frictional force in Si units Question 4 of 15 This problem has been solved! WebCoefficient of static friction is the maximum ratio of applied force to normal force with no motion. We all know Frictional force is a force which opposes motion. If we keenly observe, once you apply force to move a body from rest, there exists a point up to which the body …
