The earliest record of a pedalo is perhaps Leonardo da Vinci's diagram of a craft driven by two pedals. [1] [2] Typically, a two-seat pedalo has two sets of pedals side-by-side, designed to be used together. Some models, however, have three pedals on each side, to allow a person boating alone to pedal from a centrally seated position.
A hodograph is a diagram that gives a vectorial visual representation of the movement of a body or a fluid. It is the locus of one end of a variable vector, with the other end fixed. [1] The position of any plotted data on such a diagram is proportional to the velocity of the moving particle. [2] It is also called a velocity diagram.
A Punt Pedalo Birchbark canoe. Human-powered watercraft include prehistoric, historic and well-known traditional and sporting craft such as canoes, rowing boats and galleys. The term human-powered boat is often used for more modern craft using propellers and water wheels for propulsion. These can be more efficient than paddles or oars and ...

A treadle bicycle is a bicycle powered by a treadle instead of the more common crank.Treadles were one of the mechanisms inventors tried in order to position the pedals away from the drive wheel hub before the development of the bicycle chain or instead of it.
In physics and engineering, a free body diagram (FBD; also called a force diagram) [1] is a graphical illustration used to visualize the applied forces, moments, and resulting reactions on a free body in a given condition. It depicts a body or connected bodies with all the applied forces and moments, and reactions, which act on the body(ies).
