Sid,
You are already "polluted" by the passenger car industry where compliance is a necessity for ride, comfort, noise decrease and simply reliability: car manufacturers could not warranty a car with no bushing and just rod ends for 100,000 miles. Uprights and chassis would simply fall apart after just a few hundreds miles.
On a race car if you notice a bit of play in a pushrod rod end you just change. Or if yo have a good car race car like a Dallara there will be a user manual telling you after how many km what rod end / bearing etc... has to be replaced.
You need to put my comments in the context of race cars and/or this forum and FSAE / FS where I have been judging for many years and where I see every year real s**t boxes where compliance is awful, make the car undriveable and wasn't clearly a part of the design process.
Before even deciding if they have too much or not enough compliance (if there is such a thing as "too much compliance" for a race car), students should at least give themselves (and later on design judges) basic numbers in simulation and in workshop measurements like the ones in the attached spreadsheet.
The reality is that 95 % of them don't even know what I am speaking about!
And I am not even speaking about combined efforts (like Fy and Fx and Fz and Mz and Mx all together) or non linear numbers; just basic numbers.
I have been in racing for 40 years and I never heard any race car designer or race car engineer complaining about too much compliance! In fact every year, n very new car, they try to reduce it and most of the time they succeed.
Of course there are compromise to make with cost, weight etc... but there isn't such a thing as too much compliance!
