OVERVIEW OF DESIGN
Our design
includes a
zig-zag on an
inclined plane
at the
beginning, a
square spiral
as it descends
the track, a
small loop, a
jump, and
ends in
Pacman’s
mouth.

DESIGN AND
CONSTRUCTION
ISSUES
Working with clay
 Constructing the loop
 Having enough energy
for jump after the loop
 Lack of mass in the
marble
 Variation in materials
due to temperature
 Accuracy of tools
 Consistency of materials
 External factors

MATERIALS USED
Clay
 Scrap wood
 ¾ inch hose tubing
 Tennis ball
 Marble
 Paper
 String
 Molding strips
 Nails
 Staples

CONCLUSION

When designing a roller coaster, forces that are
normally ignored in concept questions need to be
considered. Drag, air resistance, friction, and
mass were all factored in to our coaster.
Although the project was enjoyable, we had to
apply all we learned in Engineering
Fundamentals.
