My fault here for not providing a clearer diagram. Sorry about that. I purposely left angles and distances out of the diagram to (I thought) focus on the way the levers behave as force is applied to them. You've fallen into the same sort of trap as I did previously with D. At first it really...

I understood how to run the calculations for A, B and C. But still, I appreciate your examples. Thank you. Initially, I had difficulty wrapping my mind around what was going on with D. I mistakenly thought I was dealing with two fulcrums (a compound lever similar to B, with it's multiplier...

Hi Tom, I assumed Baluncore was referring to mechanical impedance...in this context it's basically a techie way of saying size the lever to achieve the desired result with the available force. I think folks got hung up on specifics (lever lengths) whereas I was most interested in the behavior...

I should have been more clear. I understand MA. I included the object mainly as a visual but perhaps it's more of a distraction. My main interest was in understanding whether the configuration shown in D behaves like B or like C...and it appears that it behaves like C. Thank you both very...

An app called Linkage offers similar experimentation but it's Win only and I'm not running a virtual machine or dual boot on my Macs. I did model these in SimScale, Algodoo and Fusion 360 but those apps will only allow limited FEA. Basically, I concluded that D would perform like C so long as...

Good morning all, Ever since I encountered biomass brick presses I've had a renewed fascination with the use of compound levers to increase mechanical advantage. So my question is about the fulcrum location and its impact on MA. Let's say we have a simple class 1 lever A and we wish to...

Just a former engineer who will forever enjoy learning and tinkering. Thank you all for contributing to another great shared resource. I'm looking forward to participating.
