Particle Kinetics: Force and Acceleration
The design of machines to achieve maximum performance is one of humanity’s oldest engineering challenges. The design of sailing vessels and some understanding of the wind’s propulsive force go far back in history. The first sailing ship may have been designed by the Egyptians some 5000 years ago. The Egyptians learned about sail forces, as they affected steering, and placed the single mast well forward for sailing down the Nile before a constant southerly breeze. For use on the Mediterranean, the mast was located nearly amidships. Such vessels were followed by Homeric Greek ships which became more specialized and larger.
