Your top speed isn't limited to the exhaust velocity. Regardless of your current speed, energy is conserved if you tip mass overboard. For the force used to displace the exhaust, the reaction force is applied to your vehicle.
Ion, plasma, arc-jet, and the like are all about taking a small reaction mass (aka propellant) and ejecting it out the back at the highest speed possible. F=ma dictates that you can achieve a large force by tossing a large mass at a relatively low acceleration, or by tossing a small mass at a relatively high acceleration. With a big solar array or a nuclear reactor, you've got a whole lot of electricity with which to expel your relatively small amount of propellant out the back.
Awright, I'm not following. If I'm an employee earning $75k per year, my employer is contributing 50% of the SS/Medicare taxes, which is a pretty large chunk. If I'm self-employed, earning the same $75k, I get to shoulder the entire tax burden. Gross earnings are the same in both cases, the government gets the same tax revenue in both cases, but I take home less if I'm self employed. I'm not claiming to be a martyr, but the tax liability does shift onto the individual if you're self employed.
We're talking about small businesses, right? There are only a handful of guys in my shop, and every one of them is critical. We're privately held, so the "owners" are intimately involved with the daily operations. Losing one or two guys to a boneheaded policy would be catastrophic, regardless of how many thousands of folks desire employment.
Okay, I'll bite. I'm self-employed, and have been for almost a decade. I became this way because I got tired of busting my ass to put money in someone else's pocket. I now but my ass for my own benefit. I have no delusions of grandeur, but I do enjoy my freedom.
The IRS levies a penalty against the self-employed - the Self Employment Tax. I'll wager that my tax bracket is substantially higher than a "wage earner" with the same gross income. Why? Because I get to pay the extra 15.3% tax for being self-employed.
Say what? I'm a small business owner, and I don't have *any* visibility into my employee's tax burden beyond the W-2 I send them. I also don't recall being able to vary their pay on the basis of their tax burden. A tax break for my employees doesn't benefit me at all.
Were I to try to lower my employees' pay on the basis of their receipt of a tax break, wouldn't I be transferring their break to me? I would expect every one of them to quit should I pull such a stunt. With all due respect, you have your head up your ass.
That's "rolling stock," and doesn't contribute motive force by itself or as a component of a larger assembly. Would've been better if you had pointed out that locomotives are wheel-driven, but are not considered "cars."
Consider where the motive force comes from. A "car" uses traction between the wheel and the ground, regardless of how that wheel is turned. A "jet car" or "rocket car" uses the reactive force from a high-speed exhaust stream, but is still designed to stay in contact with the ground. An "aircraft" may strongly resemble a "jet car" with the aerodynamic surfaces inverted, having the intent to leave contact with the ground.
As with the legal system, intent often makes the biggest distinction.
DST is a gigantic PiMA, especially when the politicians start randomly changing the start/stop dates. I run a number of automated systems for satellite communications. Accurate time is essential for calculating communications windows and Doppler shift. I have a number of applications that got totally hosed because they calculate the DST offset internally... using the *old* dates. Being an hour early or late is catastrophic. Having a month-long blackout period is unacceptable. The apps were foisted upon me by management, and they're closed-source. One vendor doesn't support the product anymore. No hopes of editing and recompiling here, dammit.
DST made sense long ago when factories relied on sunlight for interior lighting, and you really needed the workforce to show up during the lit hours. It has not a damned thing to do with your convenience nor with "safety." DST needs to go away. It's a burden on us all, globally. And if you comprehend the global-ness of our society, you understand that DST is completely irrelevant now.
Yeah, I heard this kind of promise from the FlexLM guys decades ago. Interoperability, you control the licenses, yadda yadda. It's a turd. Individual vendors couldn't get their client implementations working well enough to "play nice" with other competing vendors applications (yes, Altera and Xilinx, I'm looking at you.) If your network and license-server topology is slightly different from the reference one, nothing works properly. FlexLM is still a disaster. This form of restriction will be too.
If you're looking for a good selection of gears, dig down into the Power Transmission / Transaxle section, and take apart one of the 2-speed Peerless transaxles. There are bevel gears, a differential, and several nice spur pairs on shafts. Sometimes this transaxle pops up for less money, but not much less.
Yes, OrCAD has a product "OrCAD CIS." The acronym officially stands for "Component Information System," but could easily stand for "Confidence Inspiring String." They've maintained the level of "suck" for years now, hoping you'll finally get aggravated and upgrade to the Cadence tools.
Speaking of OrCAD, they play the version number game. I've used the tools since they were originally introduced. v7 was rapidly upgraded through 7.1 to 7.2 for ugly bug fixes. They skipped v8 and jumped directly to v9.0. That was followed promptly by bug fixes that pushed it to v9.2. The v10.whatever releases weren't well accepted by the market. Then they jumped to v15.7, which is where we are currently licensed. Had a customer who required that release version for the drawings, so we upgraded. Funny, looks a lot like v9.2 with some cosmetic changes. We paid how much for this? and it doesn't come with paper manuals? Sheesh, what a scam. Oh looky, I see they're up to v16 now...
The throwout bearing is also known as the Jesus bearing to those who wrench on cars. Usually after rebuilding the engine, installing it in the car, and topping up the fluids, you'll notice the Jesus bearing sitting on top of the toolbox.
Bloody hell. All the changes are indirect references to another document. For example:
3 (C) in paragraph (4)(A)-
4 (i) in the first sentence, by inserting
5 after ''insured loan'' the following: ''and
6 any payments made under this para-
7 graph,''
I found a reference to FrameMaker adding the "change bars" feature in 1993. Fullwrite Professional seems to have had the "change bars" feature since somewhere around 1990. Could we please just distribute the modified final document instead of this indirected crap? It's not like the technology to do so is unavailable or "cutting edge."
Fthrust = Isp * (mass flow rate) * (gravity on Earth), which allows us to solve for the mass flow rate:
650N = 318s * MFR * 9.8m/s^2
MFR = 0.209 kg/s
With 600kg of propellant on board, you'd be able to fire the engine for 600kg / 0.209kg/s = 2871 seconds on the Earth's surface... a little over 47 minutes. At least that's consistent with the other derived number. Sorry about that, Chief.
Unfortunately, the Big Studios' profits are hindered by your convenience. Yes, you bought Harry Potter: Double-Secret Book of... Secrets, but if you don't pay for each and every viewing, how is the blue-collar stage hand or audio technician going to get paid?
Moving around in space is all about changing your velocity. There are a number of ways to effect that change - gravitational slingshot, aerobraking, big sails, thrusters... Each has advantages and disadvantages. For example, direct thrust may provide the most direct path to your objective, but the fuel requirement may be impractical. The mission designers have chosen a method of getting MESSENGER (about 1000kg of payload) to it's objective with enough fuel on-board to perform it's mission. Many variables have been considered - launch vehicle requirements, time to arrival, duration of mission, required consumables, etc. It's a horribly complex optimization.
The most efficient time/location to make orbital adjustments is apogee or perigee. If you enter into a highly eliptical orbit and wish to circularize at a much lower altitude using only a fractional-Newton thruster, yeah, it'll take a while. MESSENGER has a 650N main thruster, but only about 600kg of propellant. That equates to "not a lot" of thruster time. The main engine has a Specific Impulse (Isp) of 318 seconds. On Earth, you'd get about 318 seconds (5+ minutes) of operation. That gravitational element doesn't really apply out in space, so the available thrust-time will be longer. The NASA PDF indicates that the final orbital insertion burn will consume 30% of the propellant, and will last about 14 minutes. Extrapolating, that indicates that MESSENGER has about 42 minutes of propellant on board.
Additionally, the Fed court validated that "economic consideration" extends well beyond just cash. I think that's just as big an element as the condition vs. covenant item, because without consideration, there is no contract.
The court handed down a ruling that "exchange of money" isn't the only form of consideration, especially in an Open Source environment:
Traditionally, copyright owners sold their copyrighted material in exchange for money. The lack of money changing hands in open source licensing should not be presumed to mean that there is no economic consideration, however. There are substantial benefits, including economic benefits, to the creation and distribution of copyrighted works under public licenses that range far beyond traditional license royalties. For example, program creators may generate market share for their programs by providing certain components free of charge. Similarly, a programmer or company may increase its national or international reputation by incubating open source projects.
So the courts appear to disagree with your assertion that he didn't "lose" anything.
Man, Bob Jacobsen is fighting the good fight. If anyone has earned respect, he has.

Funny, I don't recall dozens of those "bad" magazines stuffing themselves into my mailbox (yes, the ancient metal one outside.) I don't recall the telephone (wired to the wall, of course) ringing night-and-day with offers for "enhancement" medications. Yes, direct-mail advertisements and cold-calling have existed since the respective media popped up. However, today's spammers aren't subject to the cost pressures of making a ten thousand long-distance telephone calls. They subscribe to a predatory cost-shifted scorched-earth structure that considers you (and your kids) to be necessary collateral damage. These douchebags have no respect for anyone else, and yes, we need to protect our kids from them.
Apple makes buckets of money on the software. COGS is minimal, where the COGS on hardware is pretty substantial. You can download apps, eliminating the physical media. Very profitable. Consider this too - you buy one computer, but buy many applications to run on it. The hardware is the enabler for the software purchases. It's kinda like machine tools - you'll buy a mill or a lathe, then spend 3x that amount tooling up to use the machine.
Apple has no desire to run their OS on any machine slapped together from parts. They're interested in providing a user experience, and in order to control the quality level, they need to control the platform. I can envision them having better financials if they could be strictly a software shop running on someone else's configuration-controlled hardware.

They have a good selection, and are quick to ship. We purchased many parts for our entry in Baltimore's Kinetic Sculpture race.

Yep. The worst part is that you put the Jesus bearing on top of the toolbox, in plain sight, so you wouldn't forget to install it ... again.
