Turning
Is it possible to ride a motorcycle
where are turns are not only 90º but
instantaneous? In the real world,
no! According
to the textbook, "Physics with Modern
Physics" by Randall D. Knight, the reason for
this
is that force goes
on the inside of a turn; consequently, causing you
to lose balance and possibly die.
Motorcycles do not steer
like cars; that is, you lean in the turn to
initiate a turn---for anything above parking
lot speeds. In order to
lean, the rider must shift their weight over the
fore-aft axis, thus creating a force
outside the center of
mass. When turning at high speeds, as seen in the
movie, Tron, you must create a
countersteer with that
force on the outside of the center of mass.
Countersteering is controlled by four
factors: angular
momentum of the front wheel, moment of inertia of
the front wheel, forks, and handlebars
about the steering axis.
At high speeds, countersteering takes some
strength. This is almost impossible when
making an instantaneous
90º turn. The only way to achieve this
phenomenon is in a Tron world---a world
where light
bikes are not beholden to the laws of physics.
Tron is a fantasy movie
that not only makes all laws of physics negligible
but are
impossible to
recreate in the real world.
