When a crate is being pushed across a floor moving at a steady speed in a straight line it is in equilibrium.

Support force act at straight angle to a surface.

In order to push a crate across a floor; you much push with enough force to match the friction. Then the net force on the crate is zero and it slides at a constant velocity.

In order for a plane to fly the force of air resistance must equal the force exerted by the propeller.
