The most unfun thing I've done in class is to perform FEA aynalisis by hand! Yep, constructing and solving a 20x20 matrix from a seemingly simple truss is no fun at all! But the logic is that we should understand how CAD programs operate FEA simulations...
Hmmmm...you might want to double check that Simon. I'm pretty sure that "2C8H18 + 25O2 ~> 16CO2 + 18H2O" is not a function of temperature.
However, I do agree that clean burning is not a concern when starting. Why engines run dirty under non-ideal stoic. ratios is a whole other...
As a auto tech in a prior life, I like to think about it like this......
There is no guarantee that a carbureted (note that fuel injection vehicles operate similarly, but automatically without operator intervention) vehicle will start every time. This can be dangerous on a very cold...
Yes, I think I remember a modern marvels episode on helo's that discussed that very problem early on in the development of helo's. Damn I love that show~!
Yes, very close to graduation.....I start applying for work Dec.. I know the market is tough these days, but being separated from my love is even tougher! Also, can you suggest a major that is more fun with more pay straight outa under grad?? I dare you to try! (in a joking tone)
If I may comment on this...I would say follow your dreams! I started out as an auto tech. Then a bad vehicular accident left me permanently disabled. After two years of pity partying, I went back to school for mechE, at 27 with no education to speak of. Three years later I'm a senior honors...
Power is not stored in the gear train. We assume that the process is reversible with no losses. since power=torque*omega(angular velocity) set the two equal to each other and solve. Don't forget to convert rpms to rads/sec.
I agree with Simon. A moment diagram will yield forces on the rubber. Then divide that by the spring constant of the rubber (hookes law). this will result in the displacement.
The vehicle would tumble, after slightly rising, almost immediately. This is due to the fact that the front wheels must leave the road surface first. Once the normal force from the from axle is lost, there is nothing preventing the front end from accelerating in the y (up) direction. A non-zero...
