I posted this because of a comment in another thread.
The example didn't involve lifting the weight. The weight just provides a constant torque on the wheel, nothing more. Still, the weight travels the same distance as the input and output. The constant torque makes it easier to see what's happening with the input force. What I am pointing out is that the input and output are moving exactly the same distance and arc, but the force required is increasing.
When I tried to explain why the SV suspension was progressive one of the main counter arguments was "you can't have equal mechanical motion and increasing force". I tried to give a couple of simple examples of what I was talking about, but no one understood (and in a couple of cases wouldn't even look at the simplified examples). Here's one simple example that shows you can have linear input and output, non-linear increasing force. It illustrates the concept of effective torque or lever arm, which is a simplified version of resolution of force vectors.
I'm not always right (like I assumed that there was an oil spray from the top of the connecting rod the other day. Guilty of ignorance and making a bad assumption), and I don't pretend to know everything (like I didn't know I had an erroneous circuit diagram for the 2nd gen bikes until someone posted a correct one), but this is simple mechanical geometry. Just like the rear suspension on the SV.
Let's set the record straight. You tell me where I was wrong in the past, and if I was I'll admit it in print on this site, line by line. BUT, if I disagree with a particular item I'll present my data supporting my position, you tell me why my data is bad. That's how we learn.
