Introduction



The goal of our device is to lift a 1kg
weight one meter above the ground in
approximately ten seconds.
The materials used in this design were
two dumbbells, a mouse trap, and cut up
two by fours.
None of the materials had to be
purchased.
Overview of Device Design



Our system is a lop sided seesaw-like
beam that is being held down by a loaded
mouse trap.
One end of the beam is tied to the 1kg
weight, while the other is weighed down
by two 5lb weights.
The loaded mouse trap holds down the
side of the 1kg weight and, therefore,
holding up the two 5lb weights.
Overview of Device Design


When the mouse trap is released, it allows
the 5lb weights to pull the 1kg weight one
meter above the ground using leverage.
Once the seesaw has lifted the 1kg weight
one meter, a string tied around the raised
end of the beam and a loop on the base
board prevents the beam from moving
anymore.
Summary of Stored Energy in
Device




The stored energy in our device is
potential gravitational energy.
All of the constructive stored energy lies in
the two five pound weights.
The stored energy in the mouse trap is
elastic potential energy.
This elastic potential energy causes the
release of the constructive potential
gravitational energy.
Conclusion


The overall planning and construction of
our device took approximately five hours.
The problems encountered while
constructing this device:



Dimension wise it was too tall.
After recutting, it didn’t elevate the weight
one meter.
Thus, we had to pull device apart and
rearrange so all requirements were met.
