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.

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.
