Engineering - June 2007

I'm a BS Physics major in my last year. I've got Calc 1-3, ODE, some PDE and vector calc under my belt. I want to take one more math course that applies to engineering. What should I take? (linear algebra, stats, numerical analysis etc...)

I'm trying to determine if titanium is stronger than platinum. I'll leave it up to you smart people to decide how "stronger" is defined. Any ideas or thoughts are greatly appreciated.

I have a two-door stand alone hardening freezer by Master Built. It is a year and a half old and recently has began running very loud. Its still maintains its temperature very well but is just noisy. I had a service tech out and he says the compressor is "shot".

1. Is it typical for a compressor to be “shot” in a year and a half?

2. Can the compressor be rebuilt/repaired instead of replaced?

I know that in DC voltage we have - and + polarities. and in AC voltage we don't have any - or + polarities, because they will be changed by the hertz of the voltage per second. But if the outlets voltage is AC why it doesn't obey this rule?

I mean for me the Ayers rock looks as if it's only like 70-100m high, I got so surprised when I learnt that it's way taller than the Sydney tower. It looks so small for me.

I've been working toward an engineering degree at the community college and it's just about time to transfer. Now I know the UC has a much better reputation, but money is a BIG factor. Either way graduates from both schools with a degree in engineering tend to find employment within their fields. What advantages, if any will the degree from the UC afford me.

For all you mechanical engineers out there that may know - is security clearance from the DOD required in order to design defense systems and/or military style weapons as well (specifically small arms)? Or, are you able to design these systems, manufacture, test them, and try to sell them to various branches of the service?

An example company would be Milkor USA - they designed, built, marketed their product, then sold 9000 m32 grenade launchers to the USMC, but do not appear to be officially contracted with the DOD. I could be wrong though..
