Getting the roller coaster car onto the display in the museum.

2. STANDARDS
S8P3. . Demonstrate the effect of simple machines (lever, inclined plane, pulley, wedge, screw, and wheel and axle) on work. 
SPS8. Students will determine relationships among force, mass, and motion.
e. Calculate amounts of work and mechanical advantage using simple machines
High School

3. Previously you successfully moved the Mini Mine Train coaster car into the Six Flags Museum of Rides. The floors, car and door remain intact. Nice Work!
Your new task is to investigate simple and compound machines and engineer a method by which you can safely get the coaster car up on the display stage.

4. In order to SAFELY lift the coaster car you must know the following information:
OSHA mandates that your worker apply no more than 900N of force.
The coaster weighs 4500N
This means you must have a significantly
reduced applied force.
Height of display stage: (to scale) 14.5 cm
Distance from door to stage: (to scale) 80cm
Height of ceiling (to scale) 5.5m
900 N

5. Solution
Group demonstration using your scale model (40% of your total grade)
must successfully lift the coaster car and meet the height, length and OSHA requirements
Individual engineering plan which includes (60% of your total grade):
Problem & solution discussion with diagram/picture
Calculations of IMA, AMA, ME
Force/distance trade-offs
Solution analysis

6. Process You will investigate : Work Mechanical advantage
Mechanical efficiency
Power
As they relate to:
inclined planes
Levers
Pulleys
Wheel & axle
Screws
Compound machines
