9. Calculation formula for frictional slopes

9. Calculation formula for frictional slopes		Symbol description and unit
(1) When pulling up with a force parallel to the slope	F=W*(μ*cosθ+sinθ) 〔kgf〕 F= F：Power	W： The weight of the object〔kgf〕
		μ： Coefficient of friction
		θ： Inclined angle of slope [degree]
(2) When pulling down with a force parallel to the slope	F=W*(μ*cosθ-sinθ)　〔kgf]　 F=	W：The weight of the object〔kgf〕
		μ： Coefficient of friction between object and slope
		θ： Inclined angle of slope [degree]
