jrmichler, thank you for the help. So I guess I should plan on using a larger diameter drum. Is a 6 inch drum more realistic? If that is the case, I will probably need to gear down the hydraulic motor using a chain and/or sprockets. I am still confused as to why a small electric motor can pull...

I am designing a winch to put behind my tractor, and I am going to power it using a hydraulic motor. My tractor puts out about 1000 PSI of hydraulic pressure, and the hydraulic motor I want to use is 9.8 cubic inches per revolution. I calculated that at those specs, the hydraulic motor will...

Thanks for clearing that up. The problem with the hydraulic motor, which is the thing that is producing these torque numbers, is that it has two separate modes. The first mode is 13 gallons per minute (GPM) at 600-900 PSI. The second stage is 3.4 GPM at 3000 PSI. I think when I first accelerate...

I am a little confused about your calculations. I am sure they are correct but I am just confused were the (15"/2) comes from? Like I said I'm sure your calculations are sound I am just not very experienced when it comes to calculations like that. Also, I just used ft-lbs because that is what...

Hello, I am new member here at PhysicsForum. I just wanted to introduce myself, and I am looking forward to learning about physics and being a part of a great online community. Thanks, John

Sorry for the confusion. I meant to type 20 ft-lbs of torque per motor, so 40 ft-lbs of torque total. I think an acceptable acceleration would be to get to 10 miles per hour within 3-4 seconds.

Hello, I apologize if this is in the wrong sub-forum, as I am new to this site. Anyways, I am trying to figure out how much torque is needed to move a vehicle that is about 500 pounds in weight. That is including the driver of the vehicle. For a little more information, the vehicle would have...
