| Apr 12, 2020 at 21:39 | comment | added | radkins | The one part that makes me think he still might be talking about the absolute vertical force, is in his proposed experiment, where he mentions a scale reading out a smaller number when adding weight to the system. But maybe it's just the phrasing. | |
| Apr 12, 2020 at 21:24 | comment | added | radkins | Yeah, great point! Leonardo's claims almost always come from real-world experiments (in which there will of course be friction). I see how adding friction could transfer some of the vertical load to A1 and A2, and originally I was trying to use this to understand how the absolute vertical forces on C1 and C2 could decrease as F increases. But, now that you mention it, I agree that he must have been talking about the proportional forces relative to F. How would we quantify how much the proportional force changes with increasing F? Would we need analyze the torque induced at the ends? | |

And did he mean 'the less proportion the arch transmits to the columns'? | |
