comment Is it possible to get AltGr key to work in Math.exe?
I can not get the -rawterm flag to work. However disabling the dll does work. LOL, the IT department is going to have a fit :)

comment Is it possible to get AltGr key to work in Math.exe?
@SjoerdC.deVries Yes, I'm sure mathematica is doing this! Simply put if i try to type [ in the command window before starting math.exe, no problems once I stop math.exe no problems then either. Seems pretty conclusive to me. Sure i can make a script but the entire idea hinges on interactive access. Small things like this kills big sections of my entire teaching argument. Sure i could also use Linux, but again there goes the argument. Seems pretty evident that Mathematica is continue being a second class tool at our university.

@tintin its the same calculation now just check that your on the segment or the endpoint is closest.

comment How can I simulate this toggle mechanism?
@MichaelE2, No offense taken, I understood that it was a reference to my previous comment should have put a :) instead of +1. I was wondering how do you do a While loop that terminates once it does not get any warnings. NOTE: I have no problems iwth NDSolve. The NDSolve is not wrong, in fact when you start to interact with forces/bending links it becomes the ONLY way. But here the system is deterministic (a textbook problem) assuming its rigid. I do quite a lot of mechanical simulation with Adams. Your prejudice is common in my students, but simulation is used because its more accurate.

comment How can I simulate this toggle mechanism?
@MichaelE2 Yes, but there are quite a few known analytical solutions outlined in literature. This one is generally one of the best behaving ones for a fourbar mechanism, without making the solution unstable as mentioned by MichaelHale. Please note the piston solution is not entirely trivial trigonometric manipulation, but there exists also a pretty trivial version that uses again the law of cosines. (BTW is your intention to make a arms race?)
