A crate of weight WWW remains stationary on a ramp inclined at 35∘35^\circ35∘ to the horizontal. The normal contact force on the crate is NNN, and the frictional force acting up the ramp is FFF. Since the crate is in static equilibrium, these three forces can be represented by a closed triangle of forces.
What is the angle between the vector representing the weight WWW and the vector representing the normal contact force NNN?
How must the arrows for the three forces WWW, NNN, and FFF be directed relative to each other along the perimeter of the triangle to represent equilibrium?
