Skate park Proposal
Leader: Liu Du Kai YingMember: Nicholas Lim Dexter Kuah
Name Venue Material Design Cost
Criteria
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
SC skatepark
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
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
Venue
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

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
Materials
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
Design
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

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

Cost
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”
Energy
A:
Gravitational potential
B: Kinetic, friction
C: Kinetic, Gravity, Friction
D: Kinetic, Friction
E: Gravity
Energy
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
Calculations
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 Expanded PolyPropylene. This soft pad absorbs the damage when there are impact, thus protecting the skater
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.
