Tho bicycle "loop" presents a moat
Interesting demonstration of a great
jrrtcntlflc principle, which plays Its
itmrt In preventing tho earth from
fropplng Into the sun, and tho moon
Jrom being precipitated upon tho
arth, no less than In keeping tho
ider and his wheel from falling to
tho ground when he hangs, head
downward, in midair, at tho top of
tic loop.
Centrifugal force Is tho agent con
cerned In this seemingly miraculous
fcHt, a force that has many appliances
ir everyday life, somo of which like
;o swinging of a bucketful of water
around tho head without spilling
astonish the uninitiated, whllo others
are so familiar that nobody stops to
think of them. But when applied In
the caso now undor consideration,
centrifugal forco presents Itself in a
most sensational form.
Yet, thrilling though It Is to watch
tho bold rider defying gravitation,
like a fly on the celling, without any
thing except his motion to hold him
In place, tho natural law that he
obeys is extremely slmplo aud per
fectly certain in Us operation. If he
observes all tho requirements of that
law it will never fall him, so that
his safety depends entirely, upon hlm
t;lf. Ho must develop a centrifugal forco
treat enough to counterbalance his
'.velght when ho Is at tho top of the
circle. Mathematics, knowing the
ilzo of the loop, Is able to tell him
2?w to develop tho force needed. Tho
Sirco depends upon tho velocity with
which ho moves. Ho acquires that
riloclty, not by pedaling, but by rid
ing down a oteep slope. How high
must tho starting point bo? A gen
eral rule, applying to all such cases,
is that tho elevation of the nolnt from
vhlch ho starts must bo to the olova-
Con of tho top of the loop in a ratio
exceeding that of five to four.
The air resistance and tho friction
oust all bo carefully allowed for,
tnd this Is the business of tho engin
eer who plans tho apparatus. Accord
ingly, if tho loop is twenty feet high,
tho starting platform must bo more
than twenty-five feet In height, and
tho acquired velocity must exceod
that named above. Of course, the loop
aay bo loss than twenty feet in holght
ind then all tho other dimensions
irlll bo proportionately reduced.
It is probable that, In tho actual
caso considered, tho velocity with
which tho rider arrives at tho bottom
of tho slopo and begins tho ascent of
tho circular loop Is at least thirty
miles an rour. This velocity Immedi
ately and rapidly falls off as he com
mences the ascent of tho steepening
curve, so that when he reaches tho
top ho is moving only fast enough to
tmpart a centrifugal force exceeding
his weight (or the effect of gravita
tion) by a margin suftlclently large to
Jnsuro his. safety.
As the bicycle strikes the curve of
ihe loop and begins to ascend, the
wheels nro pressed against tho track
with tremendous ftfrco and the rider
Is pitching forward with nn energy
vlilch only practice and trained mus
cles can enable him to withstand. It
Jo as If the weight of half a dozen men
had suddenly been thrown upon him
and his machine. If we estlmato tho
actual weight of bicycle and rider at
00 pounds, then it can be shown that
their combined weight, or rather their
pressure upon the track, owing to cen
trifugal forco, becomes, as they begin
the ascent of tho loop, more than n
thousand pounds; And this, too, at
the minimum speed theoretically re
Quired to carry them around. In prac
tice this pressure may bo considerably
yreator.
Here, then, would seem to ho a point
of special danger. Tho rider must bo
prepared for this Instantaneous In
crease of virtual weight. He has to
keep Ills nerves steady and his head

clear, and must retain control over his
muscles In order to hold his balance
and guide his wheel. But this Is only
a beginning.
As ho rises, in a moment he Is going
straight upward, and tho prcssuro
swiftly diminishes. When ho whirls
across tho overhead portion of tho
track and reaches tho center of tho top
of tho curvo his head Is down, his foot
nro up and his bicycle is on top of
him. They nro sustained only by cen
trifugal forco. Gravitation Is pulling
them straight downward with a forco
of 200 pounds. If tho centrifugal forco
but slightly exceeds gravitation at this
point, the rider, If ho has tlmo to an
alyze his sensations, must feel almost
ns If he wero floating like a feather,
deprived of nearly all weight.
This Is tho critical point. If tho cal
culations have been correct, there will
bo enough velocity remaining when
the top 1b reached to counterbalance
gravitation, and, even If tho excess la
slight, tho rider and his wheel will
pass on and, onco over tho center, thoy
are henceforth securo against a fall.
They will remain on the track during
tho downward Jonrnoy. Theoretically,
with a loop 20 feet In diameter, and
neglecting reslstnnco, they must reach
tho top with a velocity of nearly six
feet a second. In practice tho velocity
would have to bo considerably greater.
But consider the effects upon mind
and body of tho rapid changes .of ap
parent weight that the rider undergoea.
At the bottom of tho loop his apparent
weight was Instantaneously increased
to a prodigious amount, almost crush
ing him down upon tho handle bar.
This lasts but a moment, and then,
again almost Instantaneously, his
weight drops upon him, and at tho top
of tho loop ho seems to weigh com
paratively little, but only to bo a sec
ond later again bent over the handlo
bars by tho pushing pressuro, as tho
wheel, having gained momentum,
swings upon tho slopo leading to tho
stopping place.
It Is apparent, from what has been
said, that the principal peril involved
is personal In Its origin. The rider
must not allow his head to swim, or
his muscles to relax their control over
the wheel. Glvon perfect self-com
mand, tho danger Is reduced to a min
imum, The same forco that carries the rider
around his twenty-foot clrclo would
