The force F1 that is necessary to move a body up an inclined plane is double the force F2 that is necessary to just prevent it from sliding down, then -(Where ? = maximum angle of friction, θ = angle of inclined plane, w = weight of the body)1)F2 = w sin (θ – ?) sec ?2)F1 = w sin (θ – ?) sec ?3)tan ? = 3 tan θ 4)tan θ = 3 tan ?
