The first sentence in my post was:
Rather than using memory think about what happens when you change the motor pulley diameter. So what is the result when you use an analytic technique to the question?
The implication of my question was that he had expressed the wrong answer.
The purpose in not giving a direct answer was to try to get starsandstripes to think about the mechanics of pulleys or other similar reducers and figure out on his own what the answer is.
Clearly, if his answer was wrong, then there was only one other possibility. But still it makes sense for him to try to reason thru to the answer.
There are too many on the forum that just want an answer, and do not want to think thru in a reasoned fashion the why of an answer where this is possible.
How many can derive the constants 1.414 or 1.732 or something close to the values. What is the difference between and how to determine the RMS and average values of a waveform such as a sine, half-wave rectified, full-wave rectified, square wave, or pulsed wave?
Sometimes one does not have a reference, or memory is incorrect, and a solution is required. Prior experience in attacking a problem by yourself is useful.
