Using the FLIPPER - Size Matters
Size Matters
Does size matter? Well when it comes to Tire Flipping, the answer is a definite yes! As was shown
in the “
Foot Placement
” section of this manual, the length of the FLIPPER (TS-03 or TS-04) or the
virtually infinitely variable diameters of truck and tractor tires, optimal foot placement may vary
as a factor of the diameter or length of the device. There is something that is even more impor
-
tant to consider. When a FLIPPER or a tire is flipped, it is never completely lifted, as it is with a
barbell. When an object is flipped over, it acts as a Class 2 lever as shown in Figure 23.
When the load provided by the force of gravity (
F
G
) acting on the device is centered on the device,
the applied force (
F
R
) to rotate the device is half as much as the force of the load (
F
G
). This is due
to the perpendicular distance from the fulcrum to the force applied (
F
R
) being twice as great as
the perpendicular distance from the fulcrum to
F
G
. The total work done by the lifter is the total
weight of the device (
F
G
) multiplied by the increase in height (H
1
-H
2
), when the load reaches its
highest point (force x distance). The greater the distance from
F
R
to the fulcrum, the greater H
2
will be, when
F
G
is centered on the device. With the same total weight (
F
G
), the greater H
2
is, with
H
1
constant, the more work is done by the lifter.
Therefore, with two devices of different lengths, but the same total weight, the lifter will do more
work and apply more lifting force (
F
R
) to rotate the device to the vertical position on a longer
device compared to a shorter device. The TS-03 is only six inches shorter than the TS-04. At
weights close to 1RM this difference is apparent. Using tires of different diameters may make a
substantial difference.
