I hope your test works out OK and that you don't burn anything up. One of our former students, now a graduated engineer and mentor in his own right, pointed out recently that the only time we have ever fried an FP motor was in my garage, doing torque vs speed tests. I'd forgotten about that. It must have been back in 99 or so.
Testing is generally the best way to convince yourself that something is or isn't true. However you can't necessarily test everything for yourself, if only because there are too many things to test! In that case you often have to rely on the experience of others. In this case I can prove the answer mathematically as well as practically, and there are generations of engineering and science textbooks to back it up. The case is pretty solid, though your teacher kind of scares me. If this person is teaching Physics, they really should understand the concept of the lever. It is the Basic Machine that is operating here and any Physicist should recognize it as such. I hope it is just a lack of mutual understanding as to what you are really asking.
