Overview

When lifting a precise tapered angle cone, and in order to lift the weight, we must exert muscle forces in opposite directions to the weight of the cone. Hence its vector is directed downwards. Our goal is to squeeze the cone between our fingers. We totally press our fingers against the inclined surface of the cone to lift it, because the pressure (or action) applied by our fingers is actually angled downwards, in the same direction and the same direction as the weight of the cone.
