Consider the block shown in the figure, which has a mass m and is sitting at rest on a ramp making an angle of θ with respect to the floor.  How big is the normal force acting on the block due to the ramp?  Equal to mg sin(θ). Less than mg. Greater than mg. Equal to mg. The answer depends on the size of the frictional force.
