Problems of friction
WebWhen F is measured and m is known, the coefficient of friction can be calculated by: μ = F / (m g) (g = 9.81 m / s 2) Results from measuring F in six tests are given in the table below. Determine the coefficient of friction in each test, and the average from all tests. Solve the problem above using the Command Window in MATLAB. WebDec 22, 2024 · Where F k is the force of kinetic friction, μ k is the coefficient of sliding friction (or kinetic friction) and F n is the normal force, equal to the object’s weight if the problem involves a horizontal surface and no other vertical forces are acting (i.e., F n = mg , where m is the object’s mass and g is the acceleration due to gravity).

WebThe force of friction here, completely offsetting the parallel force of gravity parallel to the surface, is 49 newtons. And the normal force here, the force of contact between these two things, this block and this wedge, is 49 square roots of 3 newtons. So we get 1 over the square root of 3.
