I started a thread "Instant Center Location of 4link," in which I described how you could locate the instant center and determine whether the car would rise or squat. I was hesitant to take it any further as I didn't know if there'd be any interest. Though there's been only a couple of comments, I see quite a few of you have been peeking so I thought I might as well add a bit more.
The following is the necessary slope of the upper links to achieve no squat or rise:
(h(S(L)X(d)+Y(a)-Y(d))-LS(L)Y(a))/(L(S(L)X(d)-Y(d))+X(a)(h-LS(L)))
The same signs and definitions apply. Be careful not to confuse "L" with "S(L)." The wheelbase, "L," appears once in the numerator and twice in the denominator and, in each case, it immediately precedes the lower slope, "S(L)."
Now, don't you wish you'd paid more attention in high school algebra? After I retired, I actually taught high school algebra at a Christian high school. I thought I'd be able to make it interesting...for the guys, at least...with problems related to cars. I think I stumbled across the only group of teens in the country who couldn't care less! Quite a disappointment!
