Just before a skater performs an ollie, there are three forces acting on the skateboard. One of these forces is the weight of the rider, shown here with two red arrows. Another is the force of gravity on the board itself, shown with a small black arrow. Finally, blue arrows show the force of the ground pushing up on the skateboard. These three forces balance out to zero. With no net force, the skateboard doesn't accelerate, but rolls along at a constant speed.
Large power is created at the point of action by applying small power to the point of effort. Application of this concept to skateboarding makes the back wheels the fulcrum, the tail the point of effort, and the nose the point of action. Applying power to the tail causes the nose to shoot upwards. When the front foot of the skater levels the nose at a point roughly horizontal to the ground in anticipation of the tail, soon to be leveled likewise by the skater’s back foot, the process smoothly done creates the illusion of the skateboard ‘sticking’ to the feet.
If a skateboard deck is turned over to its design side, there are two complete T-shaped pieces of metal. This piece is attached to the skateboard deck with screws. The pin is a long piece of metal that is designed to turn the skateboard deck. Adjusting its tension affects the skateboard deck's turning sensitivity. Typically, longboards have looser tension than other skateboards to allow deeper turns.
One foot on the tail, (by foot I mean the ball of the foot which is just behind the big toe) the other foot is about an inch behind the bolts(screws) for the front truck. Basically, the back foot quickly pushes the tail down, and right when the tail of the board strikes the ground, the back foot jumps up… the tail of the board will follow up with the foot when the front foot slides forward slightly, which pivots the tail of the board upwards. Since the front truck comes off the ground first, getting the back truck up is the trick.
The Element Quadrant #14 board is 8-inches wide and 31.75-inches long, from nose to tail. This deck features a bare top that needs grip tape and a design on the bottom with four quadrants featuring the Element symbol in alternating red and black backgrounds. The wheelbase between the trucks is just over 14 inches while the nose is 7 inches and the tail is 6.325.
