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

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

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

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

Issues When Constructing Nails through wood Backboard Rotating wood Sidebars

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