Science of Skateboarding
The skateboard has three parts: the board or deck, the wheels, and the trucks that connects the wheels to the board.
Skateboards today are made from seven piles of sugar maple veneers pressed together with polyvinyl glues in either metal or concrete forms. The veneers usually take around 300 pounds per square inch (psi). Anywhere from three to five boards are done in each press. After 30 minutes to an hour, the boards are taken out from the press. They are laminated into a compound curve shape that curves in. The curve is called concave. After days of curing, automatic tools or hand tools are used, depending on the type of wood factory, to cut the final shape and apply the edge trimming. Then the company puts the skateboard on the market.
