From an engineering standpoint, entropy is unrecoverable waste heat.

Just to get a few things clarified. These cars were unibody with sub-frames in the front. How far is the car torn down?

Can anyone recommend a good book on weld design? I'm not looking for a general textbook on welding. I want something that specifically targets the design of joints and weld choices. Something like the welding chapter of Shigley's Mechanical Engineering Design, just much more in depth.

All "mechanical advantage" means is you have leverage. A low gear. The amount of work done is the same either way. Once you go past 1:1, you are at a mechanical disadvantage (high gear). Work still remains the same. Just count the teeth on the sprockets and compare them. It's as easy as...

In an ideal world, a 1" wide tire would work just fine. Asphalt is an imperfect surface, so you try to make up those gaps by getting more rubber out there transmitting your engine work to the road. There is a point of diminishing returns there though as far HP and tire/wheel combos. Pro...

OP, I think they call it mechatronics. I think most EE's come out of school these days with a grasp on high-level programming, digital logic and messing around with MATLAB. I've seen plenty of ME's do an EE's job but I've never seen the opposite. The math is the same with a spring-mass-damper...

Interesting stuff. Much different than I was taught or practice. Anyways, I think it would be much more productive of you to offer an answer to the OP rather than mess with the guys who give him an answer.

[/PLAIN] I can't see your pic though I'll say volumes have been written about bending metals. Sheet steel bending allowances are usually based on something like a 44% of the material thickness as far as the actual neutral axis(inside radius). This is not something engineers came up...

What kind of nut goes on these bolts?

That's a great chapter you quoted there, far better then mine. I'm not sure what you mean though. I'm assuming you're talking about shoulder bolts which is something that's not involved with the OP's question. If you're talking about fully-threaded vs. partially threaded cap screws and...

Baluncore is right on track. The dowels are used for dimensional location and the bolts are used for their tension to make the "joint stick" hence resiting shear. In other words, it's the interface of the parts being mated that resist shear, all because of the compression being put on them by...

Measure the voltage drop across a shunt resistor, the same thing people have been doing since the beginning. That's what the ammeter in your meter is doing anyways. Current, just like mass flow, is difficult to measure cheaply. Most circuits indirectly measure current by directly measuring...

Whats missing is a loss to either air or water. Grab a heat/mass textbook.

If you stay in school after your bachelors, you'll get classes geared more towards analysis rather than actual design. I think the smaller the company you work for, the more you'll be expected to design and carry out the rudimentary FE analyses. If you choose to work at a large company there...

I think "staffing agency" is a more descriptive term these days. They can deal in temp work, contract-to-hire and direct placement positions. In temp work, the agency is your employer and get's a cut of your hourly pay with no mention of actually being hired by the company. Contract-to-hire...
