i just read that description, feeling a little slow at this hour

More or less, take the diagram, but instead of using weight, your actually tightening the device and measuring the output with a spring scale. Does that make sense? Rotary power (in Newton-meters per second, N·m/s) = 2π × lever length (in meters, m) × rotational speed (in revolutions per second)...

Oh dude, your going back to flux, flux sucks

You don't drop current but you do draw it. Your house has a 100 amp service That means at any given time a hundred amps can be supplied. To actually visualize stop thinking of things as resistance and start thinking of them as a load. A microwave needs 1200W of power to nuke your pizza pop...

Can't even been to comment on your equations, but its my understanding that as heat goes up resistance goes down.

Well that's what I thought?!? Force x Radial distance But the force is exerted on a coupling which is much larger than the shaft (4" vs 1") The shaft of the motor is what they're using for the "calculation" So therefore the force exerted is across a belt which rests upon 180 degrees of the lower...

If you are applying a high voltage to a conductive material, you can induce a voltage across another if it's close, same reason why metal stuff next to a magnet becomes magnetized

Eddy Currents, Whatcha trying to do? I'm not a physicist btw.

For general terms V=IR

What exactly are you studying right now. AC/ DC I could be broad, but it would help me narrow the field a little.

And P in=P out so the motors "strength" to run something plus the "strength" to run itself for all intensive purposes is fairly accurate representation.

Torque= force x radial distance The radial distance of the shaft is 1'' the force applied at the coupler is at a radial distance of 4'' (this is where we are applying it) Furthermore the belt that is applying the force is not perpendicular to the coupler it in fact encompasses the lower 180...

Voltage is a potential. ie biggest dude ever stands in front of you. If you don't make him mad no harm no foul (lets call him 480v). He could potentially kick your butt, but he probably won't. Now if you make him mad and he takes a swing at you (better run this guy can punch a few amps), misses...

Homework Statement Hey guys, not much of a physicist. But, I am fairly certain I am right. We are using a "prony brake" at school to calculate torque in a motor. To me the amount of force supplied should equal the amount of force the motor can turn ie: when the motor stops the force applied on...
