You have me curious about the clutch. Here is what I think. Most
mechanical automobile gauges have some type of mechanism that involves a
spring and something that opposes the spring, like an electric magnet
operated by a spinning cable. If you were to accelerate really fast, like
you are describing, you should expect the needle to overshoot the correct
mark by a significant amount, then oscillate about the equilibrium point,
the gauge being almost unreadable. To correct this you overdamp the system
so it relaxes exponentially to equilibrium. Your car is fine; Newton is
fine; your gauge has a delay.
I would hate to think of that during an interview.
By the way, I am a high-energy particle physicist/theorist, though I did
spend a lot of time in a chemistry lab when an undergrad. I do software
these days -- pays better than quantum field theory.
I have tutored, TA'd and taught many courses. The problem is not so much
the curriculum, but the quality of the students. Good students are curious
and go looking beyond what is required. Most are lazy and do nothing more
than what is absolutely required.
Students should learn theory in the class. Then they should work with a
research group in the lab on the side and try to do internships in the
summers. That is the only way to cover all of the bases. I worked as an
undergraduate RA in graduate research labs while I was a student, and that
is just part of the experience. Any decent engineering department should be
working hard to get students into internships and/or labs.
Unfortunately it is very hard to get good students these days unless you are
in the school of business. There you can be lazy and only marginally
intelligent and still make much better money than a hard working, very
intelligent engineer. (It's even worse for research physicists!)
