Question

The coefficient of friction between blocks is us = 0.4, at what angle will the block start sliding if it is initially at rest?

*** Kindly fill up the respective blanks.

The coefficient of friction between blocks is us = 0.4, at what angle will the block start sliding if it is initially at rest? Solution Let us obtain the net force in the axis perpendicular to the inclined plane. By virtue of the first law of motion (equilibrium), the net force is 2 F perpendicular = n - Fgperpendicular = Thus, the normal force is n = m cos On the axis parallel to the inclined, the net force is 2 FI| = Fg|| -fs,max = Substituting the forces, we get the following: mg smg By simplifying, we get the following: tan(theta) = mus %3D Thus, the angle that the object will slide is: (rounded of to the ones)
