Motor Torque

AI Thread Summary

To calculate torque for a motor driving a trike powered by a dynamo, it's crucial to understand the efficiency of the power transfer. Directly pedaling to the wheel via a chain is significantly more efficient, achieving up to 99% efficiency, compared to the less efficient route of using a dynamo to power a motor, which may drop below 50% efficiency. Including a battery further decreases overall efficiency, complicating the power transfer process. Therefore, for optimal performance, a direct mechanical connection is recommended over an electrical system. Efficient torque calculation is essential for maximizing the trike's performance.

I want to drive a trike but using dynamo at pedaling and the electrical power given to 400 watt motor
So any suggestion what i can do best

Why? What problem are you trying to solve?
Pedal > chain > wheel is much more efficient (up to 99% ) than pedal > dynamo > motor > wheel ( could be lower than 50 %)
It gets even worse if you include a battery.

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 'Cantilever help'

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
