'09 Scrambler 2009# 3 This is what you want it to do… The intent of the event is to have a falling mass propel a cart carrying an egg down a track as quickly as possible and end up with the egg as close to the terminal wall without… as quickly as possible!!!
'09 Scrambler 2009# 4 DOING THIS!!! Now you know why it is called SCRAMBLER.... or in this case SUNNY SIDE UPPER!!
'09 Scrambler 2009# 6 Construction Entire device – 0.75 m square Could be 1 or 2 parts Falling mass – 1.50 kg (NEW) ‡ GPE & KE ‡ Could be transferred ‡ Additional energy could be used to brake No electronics at all Must have 5 x 5 x 1.25 cm thick flat rigid egg mount. NO BACKSTOP!!! Egg: 5-15 cm from floor, 2 cm in front of foremost part Both ends of egg must be viewable
'09 Scrambler 2009# 7 Competition Track: 2 m wide, 8-12 m long ‡ Half meter (Regional & States), 0.1 m (Nationals) 10 min. to do 2 runs Tip of egg on starting line All parts behind and within 2 m Hold either cart or mass Allowed only 1 egg – if broken on first run, NO second run Must wear safety spectacles (NEW) Egg transport MUST start level with track (NEW) Alignment
'09 Scrambler 2009# 8 Scoring Run Time -> ‡ complete stop Stopping Distance -> ‡ Distance from the pointed end of egg to centerline of the terminal barrier (cm) (NEW) ‡ Lowest possible value: 0.1 cm (NEW) Performance Value -> ‡ 2 x Run Time + Stopping Distance Whatever run gives you the best ranking is the one counted
'09 Scrambler 2009# 9 Penalties 2 types: Run and Construction ‡ Run penalties ●Egg broken ●ANY part of egg transport contacts wall INCLUDING THE EGG (NEW) ●Transport runs outside lane (at ANY time) ●Transport doesn’t travel at least ½ the track distance ‡ Construction penalties Ranked tiers
'09 Scrambler 2009# 10 Building suggestions First and foremost, build early, practice, log, and calibrate as many runs as possible. Use a plastic egg filled with any material to around 65 g Always build just under/over the dimensions!!!! Make the transport as light as possible Perhaps try some different floor surfaces Did I say calibrate? Strongly consider using aligning devices since you need the transport to go as straight as possible
