Hi I would like to know, does the torque required to turn a pulley increases if you increase the tension? I have a system like this: pulley motor pulley car and a belt goes around this system, the motor is included in the system via a gear that's attached to its shaft, so as the motor turns, so does the gear, and the belt would drive the pulleys and move the car to overcome friction. my question is, if I have a very strong tension in my belt that goes around this system, will it increase the torque required for the motor to turn the gear? I don't think it could as that would imply the higher the tension the more energy consumption, but I really don't see where else the energy would be converted to if I run the motor at the same speed. I am trying to do a force analysis on the gear but it is proving to be troublesome as I don't really understand how tension in a belt/rope works as it is moving around a pulley system, this is beyond what I've learned in my physics, and even engineering courses, and I would appreciate it if someone can enlighten me.
