Dear PF,
This is my first post, so please pardon any faux pas.
I've had some difficulty wrapping my head around the concept of torque. I have taken multiple classes on dynamics, statics, etc. I understand it theoretically, but not practically.
A friend presented me with this problem (noncommercial) that requires an application of torque. He's moved on from the project, but I'd still like to understand it. Any help is very much appreciated, thank you!
// Problem
What motor is needed to turn a camera dolly supporting both a man and a camera, as shown in the attached picture? I've attached a drawing, along with the work I've down on the problem.
Here is a link to a selection of electric motors, rated by horsepower, rpm, and AC/DC. How do I make a selection? How do I know a motor will provide enough torque to start them spinning and get them to at least 10 rpm?
If any more information is required, please let me know. Thank you in advance.
