If a 11Kg crate sits on a ramp with a 14 deg. incline, what force must the ramp exert to keep the crate from falling (Fn)? ?

    The friction force must equal the downslope component of the weight:

    f = m*g*sinΘ = 11kg * 9.8m/s² * sin14º = 26 N

    Hope this helps!

    Friction force = -gravit. force = -m*g*sin = 11*9.806*0.242 = 26.1 N
