Why not just build micro-controllers that contain everything on it?
Many manufacturers are doing just that! You can buy microcontrollers now that contain flash memory, ram, a/d and d/a conversion, dsp, even a fpu right on chip! The limitation is at some point the chip becomes so specialized that it has limited application. That means it will not sell in very large quantities. The chip makers have to balance these factors when deciding how much stuff to put on a microcontroller. Also at issue are interconnects inside the chip as well as package pinout. Some chips now have so many pins on such a very fine pitch that soldering/assembly is becoming more and more difficult. Dissipation of heat is also a major factor as the microcontroller increases in complexity.
What happened in Washington State in 1990?
The 1990 Goodwill Games, something like a minor Olympics, were held in Seattle, Washington.
Windows 93 is really hard to prove but it was actually Windows Chicago which is the codename for Windows 95 and the earlier version for 95. Windows 97 and 99 was real but it got canceled. Windows 97 was NT 4.0 or 5.0. And Windows 99 got canceled because Microsoft moved on to Windows 2000.
Is it possible to transform ice to vapour directly?
The process is called sublimation. Sublimation is an endothermic phase transition that occurs at temperatures and pressures below a substance's triple point in its phase diagram.
This process can be seen with dry ice: solid carbon dioxide evaporates into the gas without becoming a liquid first.
What does the word junction mean?
If you are looking at a wiring schematic, junction refers to a point where two or more wires are connected together to complete a circuit.
Can a mechanical advantage be a fraction?
Yes, mechanical advantage doesn't need to be a gear type which you can always count the ratio of teeth to a full number. A pulley type gear can be of a fraction in gear ratio.
==========================
Think of a Class-1 lever ... like a see-saw ... that's 5 feet long,
with the fulcrum 2 feet from one end:
-- When the effort is applied to the longer side, the MA is 11/2 .
-- When the effort is applied to the shorter side, the MA is 2/3 .
Classification of instructional materials?
An example of instructional materials is a guide that comes with a product that has to be put together. Another example may be a guidebook that comes with the purchase of a new video game that leads the player through the game.
What gear does a marine carry?
It depends on the mission, but usually a typical combat loadout is: Issued rifle: m4/ with m203 grenade launcher, K-BAR M9mm pistol (gunners and commanders only). 1 or 2 m67 hand grenades. (7) 30 round magazines(5.56) Flak jacket w/ SAPPI plates kevlar helmet knee pads elbow pads protective gloves eye protection And night vision goggles: PVS-7B's (both eyes) or PVS 14's ( one eye)
That is when a piece of equipment has a failure and will not work.
a) Put 2 of the resistors in series to make a 200 ohm resistor. Then put the 100, 100, and 200 ohm resistors in parallel for 40 ohms. b) Put 2 resistors in parallel for 50 ohms. Put the 50, 100, and 100 ohm resistors in series for 250 ohms. c) Put 2 resistors in parallel for 50 ohms. Repeat with other 2 resistors. Put the two 50 ohm resistors in series for 100 ohms. This configuration can withstand 4 times the wattage of each individual resistor.

What are the 4 principles of training?
There are more than four:
SPORT FITT
Specificity - Choosing a type of exercise that is related to the What_does_each_letter_in_sport_fitt_meanyou do.
Progression - Gradually progress/increase the What_does_each_letter_in_sport_fitt_meanyou are doing.
Overload - Doing more exercise than what the muscles are used do.
Reversibility - The muscles slowly decrease in strength due to a stop in exercise.
Tedium - Varies of different What_does_each_letter_in_sport_fitt_meando prevent boredom.
Frequency - How often you exercise.
Intensity - How hard you exercise.
Time - How long you exercise for.
Type - The type of exercise you do.
What subjects or majors can you do if you're good at math?
Science, especially physics; any engineering discipline; architecture; economics and finance; computer programming; statistics...
Why does a rolling ball stop rolling?
Friction translates lateral motion to rolling motion, but it can slow down a rolling ball because it opposes the motion of the ball's lower surface to do so. This removes momentum from the ball.
When a ball combines rotational and translational motion (rolls), friction acts in the opposite direction of the motion. This in turn should produce a torque by the frictional force i.e,[u.m.g*R] where R=radius of sphere , u = co-efficient of friction. The torque produced should increase the angular acceleration and therefore the body should rotate with greater speed, but as we know, the rolling sphere stops after a certain time.
REASON: When a sphere rolls, the surface in contact with the sphere is depressed and the surface just in front of it is raised. So when the rolling sphere strikes this raised surface, the normal reaction instead of passing from center of mass passes through a little bit away in the forward direction of the motion. Therefore the torque produced by this is greater than the torque produced by the frictional force, and opposes the motion of the body until it comes to rest.
basically induction moters are use for the eot crans.
one for long travlling , one for cross travlling .
What is the force exerted by the Tacoma narrows bridge?
the force was torsion. the wind made it bend like silly puddy ************** The force exerted TO the Tacoma narrows bridge was initially the wind resistance. The wind resistance caused the whole bridge to act as a system with forced vibration with damping.
Who is george valentine Peterson?
George Valentine Peterson was born a twin on February 14, 1926 and immediately after his birth his mother died. George V. Peterson suffered a childhood injury by falling from an apple tree and contracted polio at age 4. After his injury he was hospitalized and strictly bedridden for 8 years. After being told he would never walk again he defied the odds through faith and determination and regained the use of his leg. He now walks with a distinct limp but it did not stop him from having a successful and full life.
His education gained him employment with several major Corporations where ultimately he would land a job at JPL and NASA where he would make world history.
He is now 88 years old and lives with his wife Irene in Georgia. He has four children and several grandchildren.
If a hot wheel makes a loop how fast does it need to go if it was scale size?
Regardless of the mass of the vehicle, the square of its speed (in meters per second) divided by the radius of the curve of the loop (in meters) must be greater than about 10 meters per second squared. That is to say for a car travelling at 144 km/h (89 mph), the loop would have to be a circle with a radius of no more than 160 m or a diameter less than a thousand feet. A hot wheels car in a loop that is about a foot and a half in diameter must also meet this criteria, but it can easily do so at the pokey speed of 5 mph.
What is the purpose of the thrust wear down or low thrust oil pressure trip?
To prevent excessive axial movement of the rotor.
