The Sandtrap Purpose Overview To Lift a 1kg mass 1m in 10 sec The device is built to be as inefficient as possible To start with, we release a .25kg mass that rolls down a ramp and hits another .25kg mass attached to a stopper that releases .5kg of that fills into a bucket already filled with multiple masses that is equal to 2.5kg. When filled the bucket has a total mass of 3kg. That is attached to a pulley system that then spins around a central shaft that essentially winches the 1kg mass up to approx. a height of 1m.

ENERGY!! For our first device we calculated the Gravitational potential energy to be .623J. The second object was found to have PEG of .374J. Also for our final object, the bucket, we had a PEG of -3.11J since our Datum was set at the bottom of our device and not the floor

Construction! In designing our project we met once to design and brainstorm in Hodges Library We then held regular build sessions throughout the project build time span During these build sessions we had to sometimes brainstorm on the fly and come up with quick fixes, not always sticking to the plans. Finally we met the day before the due date to test and finalize our design

Conclusion In all we found that our device, while complex, does complete required task but does not always take exactly ten seconds In all the total cost was $18.63 Also the total build time including the design process took a total of 10 hours.
