Skateboarding is the best and worst thing that’ll you’ll ever have the pleasure of tearing your hair out over. In a typical day of skating, you’ll get hurt, you’ll get incredibly frustrated, and eventually land a trick that’ll make it all worth it - if you’re lucky. Choosing a skateboard is fairly simple if you know what shape and width you like. If you’ve been skating awhile, you’re probably fairly familiar with what board brands you like skating. If not, there are a number of resources to help you choose the best skateboard for your skating style. Continuing to read this little spiel is going to take the least amount of effort on your part.
In fact, we can work out how you need to steer the skateboard. Tracker has a nice feature that we'll call 'force arrows'. These arrows show you how much force acts on an object at every instant, and in which direction the force acts. So for example, if you were to kick a ball into the air, while the ball was mid-flight, this arrow would always point down and be the same length, even though the ball is moving forward. That's because the only force acting on the ball is gravity, which pulls it straight down, and acts with a constant strength. (For those of you who've studied physics, these arrows denote the acceleration of the center of mass, which by Newton's second law is proportional to the net force acting on the skateboard.)
A skateboard deck is made up of curved layers of wood that are combined with glue. Then, the skateboard deck is trimmed down to a board shape that is practical. Trucks are typically made of aluminum or other metal alloys. They are made by melted metal formed by a mold and later drilled into the skateboard deck. The wheels are formed the same way, but with polyurethane. They are attached by ball bearings to complete the product.
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.
The following descriptions cover skateboard parts that are most prevalent in popular and modern forms of skateboarding. Many parts exist with exotic or alternative constructions. A traditional complete skateboard consists of the deck (often with griptape applied on top to enhance traction), trucks (with urethane bushings), wheels (with sealed bearings), bushings, nuts and bolts to fasten the truck and wheel assembly to the bottom of the deck. Older decks also included plastic parts such as side, tail, and nose guards.
4 amazing skateboards in one nice lot. 1. 1990's Tony Hawk Conplete Skateboard, original falcon 3 design. With Rekon trucks and firelite classic wheels. 2. Sk8mafia Lucero deck. Signed by John Lucero. Brand new deck. 3. 1031 deck signed by entire team on a brand new creepy crawl deck. 4. Brand new super rare Big Mess deck with Blast design. This deck is extremely rare and is a must have for any collector. Both the signed decks are personalized to a guy named Jason that owned a skate shop here in Grant's Pass Or. Those guys were on his wall for a long time before he went out of business. If you have any questions or concerns please let me know. Thanks for looking. Steve
