Paul you called this the silly season, so can I ask a silly question. A search
lead me into too much cosineactivity.. if you get my drift.
If I have an electric drill vertically doing some revs, and in the chuck I
have a very unbalanced flywheel, does the load due to the imbalance, ie the
harmonic vibration , add to the electrical input load of the machine.? For
example in the following circumstances, would the power input differ in.
a. when I allowed the motor to swing in a circle , as it would be wont to
do, take power load reading.
b. And when I held it rigid immovable. preventing the vibration, take power
load reading.
Which leads on to an experiment,
If I were to fix this motor to a fixed pivot arm that was free enough to allow
the motor centre to vibrate over say 5 mm per revolution , which was translated
due to the pivot arm length , into a vibration of 20mm length at the other end.
Would a piston load put on that lever add a load to the motor input power. ??
Philip.
the math was no help coz it involved complex centrifugal forces involved with
flywheel action.. Also ignore all frictional and windage losses.
