This is what I have and I have a feeling that I do not understand. 11. A box with a mass of 22 kg is at rest on a ramp inclined at 45 (degrees) to the horizontal. The coefficients of friction between the box and the ramp are: (mu(s): o.78 and mu(k): o.65) a) Determine the magnitude of the largest force that can be applied upward parallel to the ramp, if the box is to remain at rest. Fa = Fgsin45(degrees) - mu(k)Fncos45(degrees) =53.4N b) Determine the magnitude of the smallest force that can be applied onto the top of the box, perpendicular to the ramp, if the box is to remain at rest. Fa= Fgsin45(degrees) + mu(s)Fncos45(degrees) =271.324N So tell me, where di I go wrong?
