  1. Skate park Proposal Leader: Liu Du Kai Ying Member: Nicholas Lim Dexter Kuah

  2. Criteria • Name • Venue • Material • Design • Cost

  3. SC skatepark • SC stands for super crazy • This is to tell students to not only study like crazy, but should also learn to play like crazy • Furthermore, they can also revise their physics components while playing

  4. Venue • Beside the basketball court • Most of the time, not all courts are used at the same time • Convert one court to become a skatepark • Noise generated would be same as that of people playing basketball • Far enough from classrooms • Aesthetically, since the basketball grounds are concrete, the colour of the skatepark would be very similar, thus blending in

  5. Venue • Easily accessible, just beside canteen • Basketball court big enough • Dimensions: 84 feet by 50 feet • Dimension of proposed Skatepark: • 55 feet by 35 feet • http://www.basketball-goals.com/basketball%20court%20dimensions.htm

  6. Materials • Surface: Masonite • Reason: Smooth skateboard/inline surface, thus reducing friction between the surfaces • Generally cheaper than the other common surfaces like metal and concrete • Can last 1+ year outdoors, thus reducing maintenance fees as only need to maintain once a year • Image from: congdonlumber.com

  7. Materials • Body: Plywood • Reason: One of the cheapest materials • Easy to assemble and very available, thus making it very cheap • http://suburbanrails.com/cgi-bin/WebObjects/PWDA.woa/wa/loadPage?pageId=2013

  8. Design • The skate park design accommodates to both expert skaters and beginner skaters • There will be steps leading up to the right side of the skatepark • By starting on the high end on the right side, one can enjoy the thrill as there will be some “air time” • By starting at the lower end on the left side, beginners then can safely move to the other side

  9. Cost • Split into costs for body and costs for surface • Body: • A 10,000 Square Foot Wood Skatepark would cost between $8,000 to $25,000 per 1,000 square foot • Pricing is based on quality • So, pricing of wooden body would range between : • ((35*55)/1000) * 8000 = $15400 • ((35*55)/1000) * 25000= $48125 • http://suburbanrails.com/cgi-bin/WebObjects/PWDA.woa/wa/page?id=7595&name=Skateparks%20F.A.Q.%20-%20How%20Much%20Do%20I%20SPEND%20/%20How%20Much%20Does%20A%20Skatepark%20Cost?

  10. Cost • Surface: • Masonite siding costs $1 to $2.75 per square foot • So costs for our surface would be : • (35*55) * $1 = $1925 • (35*55) * $2.75 = $5293.75 • http://www.howmuchisit.org/masonite-siding-cost/

  11. Energy • In our skate park, the energy acting on participants will go as follow: • Let us label the highest point on the right as “A”, the bottom point on the right as “B”, the peak of the center as “C” the bottom of the left as “D” and the peak of the left as “E”

  12. Energy

  13. Calculations • Initial potential energy= mgh • (75)(10)(8.04) = 6030 J • Friction Coefficient: 0.3 – 0.4 ( about the same as wood with metal of the wheels ) • Friction = 75 * 0.4 = 30J • Amount of kinetic energy converted = 6000 J

  14. Safety Precautions • Before skating, all skaters should always wear a helmet • Ensure that: • The helmet is made of a strong and durable material. Make sure that it is a skateboarding helmet, not a bicycle helmet. Bicycle helmets are made of thin materials that crack upon impact • The helmet should have protective pads known as ExpandedPolyPropylene. This soft pad absorbs the damage whenthere are impact, thusprotecting the skater

  15. Safety Precautions • The skater can also wear elbow and knee guards • This ensures less friction between the surface and the skater thus preventing abrasion • The skater should wear wrist guards to support the wrists in case he falls, because there is a tendency to land on your wrist.
