A box remains at rest on an incline. The force of gravity acting on the box is directed down and has a magnitude of 10.0 N. The angle the incline makes with the horizontal is 40.0 degrees - this is the maximum angle the incline can have before the box starts to slide. Calculate the magnitude of the normal force acting on the box. Calculate the magnitude of the force of static friction acting on the box. Calculate the value...

A box (mass 25.8 kg) sits on a rough incline that makes an angle α = 28.1o with the horizontal. A massless string is tied to the box, runs parallel to the incline, passes over a massless, frictionless pulley, and is tied to mass M hanging on the other end. Assume μs = 0.455 is the coefficient of static friction between the box and the surface of the plane. Find the maximum value of M, in kg, for which this...
