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 ?
