Calculation of Torque (Not Homework, just )

AI Thread Summary
To calculate the required torque for moving the shaft at 35 RPM, it's essential to understand the resistances involved in the application. The net torque at constant speed is zero, indicating that the applied torque must balance out the resistive forces. Identifying these resistances is crucial for determining the appropriate torque value. Once the torque is calculated, it will inform the selection of a suitable magnet resistance motor to replace the load disc. Accurate torque calculations are vital for effective fixture fabrication.

Need some help to fabricating a new fixture.

Currently our application shown in the picture. but i need to calculate the torque required to move the shaft. IF can, the speed of rotation should be around 35 rpm.

I need the torque value before i can determine what model of magnet resistance motor that i can use to replace the load disc.

Thank you.

For a rotation at constant speed, net torque is zero. You need to know what resistances there aere.
 

Thread 'Bubble formation in 4 mm gap vessel'

How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Find 3D Printer & Software Resources for Prototype Creation'

I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
