thank you kallog

now finaly we can connect the dots.

there is no force applied to the pipe because the mass changes direction.

the only forces that apply are the (+) and (-) forces
that the mass applies to the pipe while the mass passes
through the turnarounds.

and the (+)force that is applied to the pipe while the mass
is being accelerated.

these forces are all the same magnatude , therefore
there are 2(+) and 1(-)

the positive forces win , the negative forces loose.

since the total force that the mass can present to the first turnaround is the force that is the product of its mass * its velocity.
and
since the total force that the mass can present to the second turnaround is the force that is the product of its mass * its velocity.

the two forces cancel each other out

the only remaining force is the force that accelerated the mass.

and that force presses against the pipe causing the pipe
to accelerate.

therefore the pipe gains acceleration each time the mass is accelerated and the pipe continues to move in a direction.

with only 1 mass it will accelerate and then jerk back and forth and then be accelerated again then jerk back and forth again etc...etc...etc.

but the jerking back and forth will not stop the pipe from constantly gaining distance away from its initial starting point.


3/4 inch of dust build up on the moon in 4.527 billion years,LOL and QM is fantasy science.
