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
