    Lever Non-linear
Click For Summary
SUMMARY

This discussion focuses on non-linear levers, specifically in the context of mechanical engineering applications such as stretching a rubber band with increasing force. The conversation clarifies that the mechanism in question is more accurately described as a cam rather than a lever. Users are encouraged to utilize online resources to calculate cam profiles suitable for their designs. Practical advice includes using cardboard or plastic for mock-up designs to facilitate trial and error in the design process.

PREREQUISITES
  • Understanding of mechanical engineering principles
  • Familiarity with cam design and mechanics
  • Basic knowledge of force application and material properties
  • Experience with prototyping techniques using materials like cardboard or plastic
NEXT STEPS
  • Research cam profile calculations for specific applications
  • Explore mechanical advantage in non-linear systems
  • Learn about prototyping techniques for mechanical designs
  • Investigate the physics of elastic materials and their force characteristics
USEFUL FOR

Mechanical engineers, product designers, and hobbyists interested in non-linear mechanical systems and prototyping techniques.

Firstly, this is a great forum!

Maybe this is more of a mechanical engineering question, but ...

Can someone help give me some examples of non-linear levers? I want to be able to stretch a rubber band with factored-increasing force. Like a reversed camber on a compound bow.

I hope I asked this correctly. My physics vocabulary is limited- but improving with the help of this forum.

What you are dealing with is actually a cam rather than a lever. A quick Google should turn up lots of information about how to calculate the profile to fit your needs. I can't do math, so I always work mine out using cardboard or plastic pieces for mock-up trial and error design.
