The problem is that the clown won't be able to move such a heavy
ladder just by leaning from side to side. If it really was several
tons, he'd have to move a long way horizontally to get enough leverage
to tip it. You can see this by finding the center of mass of the
ladder-clown system and look what the clown has to do to move the
center of mass away from between the legs.
Although it seems that a tall thin heavy tower would be unstable and
easy to unbalance, the weight actaully makes it pretty hard to tip
over. Once it starts to fall, yes it can be hard to stop, but getting
it to sway takes more force than a light tower.
A Harley can be what, 800 pounds? The legs are close, like a skier's
legs during fast speed, and a gentle balancing is needed to keep the
weight right in the center. The legs are so close that they barely
shift the weight right and left off the center. Barely, but sufficient
to tip the weight off one ski to the other and back. This is not a
fixed heavy structure as you imagine with wide ladder legs.
A man can balance a ton, but yes, once it starts falling it falls
relentlessly to the side. I had that with a motorcycle, one fourth
the weight of a Harley, it was embarrassing.
You tip it to one leg (ski), but not further, you tip it to stand in
the
other leg (ski), but not further. Acrobatics. However below is a
ton or more weight shifts between two regions and one can
your large and small gears to minimize the down motion
while the force of the weight is extracted. Only a few pounds
of push may be needed on this very tall and stiff structure to
balance it slightly off the central position where it stands on
both legs. You build it so narrow and tall that it stands in the
unstable point of falling from the slightest push to either side,
then have something that blocks the fall and have it easy to
push it back, but the result when it tips a tiny bit to one side
is that on the bottom the weight moves, balances to stand
from one ski to the other with the whole weight of this standing
robot than a ladder, and that is a lot of weight. I used ladder
because it is how I invented this, through a ladder that is
hard to tip to stand on one side of legs at by pushing it
at the bottom but easy to tip at it's top.
