Web4 Answers. Sorted by: 1. The equation of equilibrium in the vertical direction is F sin θ + F f − m g = 0, where F f is the friction force (if its sign is positive, it is directed upwards), so F f = m g − F sin θ. However, if m g − F sin θ > μ s F cos θ, the problem does not have a solution (the block cannot be in equilibrium).
