Although the oar can be conveniently thought of as a lever with a " fixed " pivot point in the water, the blade moves sideways and sternwards through the water, so that the magnitude of the propulsion force developed is the result of a complex interaction between unsteady fluid mechanics ( the water flow around the blade ) and solid mechanics and dynamics ( the handle force applied to the oar, the oar's inertia and bending characteristic, the acceleration of the boat and so on ).
