2. Device Design
Our primarily wooden device goes through a series of ramps and rotational procedures to raise a UT banner and start the next group’s project

3. Operation Begin: Block of wood removed Marble through tubing
Marble onto seesaw
Marble into windmill
Marble down ramp
Marble hits larger stationary marble
Finish: Large marble starts pulley, which pulls up banner

4. Concepts used: Conservation of Rotational Energy
Conservation of Linear Momentum
Conservation of Translational Energy
Center of Mass

5. Calculations Translational Energy Work= Force*distance Collision
m1v1+m2v2=m1v1’+m2v2’
Center of Mass:
R=(m1r1+m2r2)/(m1+m2)
Torque
T= Force* perpendicular distance

6. Issues When Constructing
Nails through wood
Backboard
Rotating wood
Sidebars

7. Conclusions Creativity was necessary when constructing
A layout before getting started is key
Budgeting was key
We learned real-world applications of physics
