Transfer of torque - wheel to wheel contact

AI Thread Summary
To calculate the torque on the 15mm wheel in a system with a 100Nm motor and varying wheel sizes, one must consider the gear ratio created by the diameters of the wheels. The torque can be determined using the relationship between the input and output wheels, treating them as gears or pulleys, assuming no slip. If slip is to be included, it complicates the calculation, as it would require additional factors to account for energy loss. The discussion emphasizes the importance of understanding torque transfer in mechanical systems. Accurate calculations are essential for effective power transmission in this setup.

Hi all,

I am trying to calculate the the torque of a system which uses various size wheels to transfer power.

Explained:

A motor, of 100Nm torque, 40000 rpm, has a shaft of 7mm diameter in contact with a wheel 20mm in diameter. This wheel is in contact with a 15mm wheel.

I need to work out the torque of the 15mm wheel.

Any help would be much appreciated.
 
Engineering news on Phys.org
Assuming no slip between the wheels you treat them like gear/pulleys.

Do you know how to work out the change in torque on pulleys or gears?
 
Thanks!

That's the route I have been traveling down but wasnt sure if that was correct.

Is it possible to include slip?

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...

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
