What is loft command in auto cad?
The loft command makes a solid or surface between several cross sections
What does a milling machine make?
A milling machine is usually capable of cutting a wide variety of metals, ranging from aluminum to stainless steel. Depending on the material being cut, the machine can be set to move at a faster or slower pace. Softer materials are generally milled at higher speeds while harder materials usually require slower speeds. In addition, harder materials often require smaller amounts of material to be milled off at one time.
When engineering controls are adequate what other forms of controls can be implemented?
physical and administrative
A .rft stands for Rounds For Time. In a .rft workout, one has a set amount of work to do and how long it takes to accomplish these tasks are stated.
What is the difference between scientific notation and engineering notation for writing numbers?
In both notations a number is represented in the form a*10^b where a is a real number and bis an integer.
In scientific notation, 1 <= a < 10 and b is any integer.
In engineering notation, 1 <= a < 1000 and b is a multiple of 3.
Which is worlds most dangerous missile?
The Russian-made SS-N-25 Onyx. Improving on the previous "Sunburn" iteration; the Onyx can reach cruising speeds of Mach 2.9 and Mach 5.7 in a dive. The incredible terminal-velocity of a single Onyx missile makes it a threat to any Aegis warship. It is thought that a single impact of an Onyx with a convetnional warhead would sink a US carrier.
Why did they turn the external tank on the space shuttle orange and not leave it white?
Actually, it is originally orange from the insulation they use, but they used to paint it white. They stopped painting them white to save weight on paint, I think like 600 pds or so.
What is future of mechatronics and control engineering?
A mechatronics engineer unites the principles of mechanics, electronics, and computing to generate a simpler, more economical and reliable system. Mechatronics is centered on mechanics, electronics, computing, control engineering, molecular engineering (from nanochemistry and biology), and optical engineering, which, combined, make possible the generation of simpler, more economical, reliable and versatile systems. The portmanteau "mechatronics" was coined by Tetsuro Mori, the senior engineer of the Japanese company Yaskawa in 1969. An industrial robot is a prime example of a mechatronics system; it includes aspects of electronics, mechanics, and computing to do its day-to-day jobs.
Engineering cybernetics deals with the question of control engineering of mechatronic systems. It is used to control or regulate such a system (see control theory). Through collaboration, the mechatronic modules perform the production goals and inherit flexible and agile manufacturing properties in the production scheme. Modern production equipment consists of mechatronic modules that are integrated according to a control architecture. The most known architectures involve hierarchy, polyarchy, heterarchy, and hybrid. The methods for achieving a technical effect are described by control algorithms, which might or might not utilize formal methods in their design. Hybrid systems important to mechatronics include production systems, synergy drives, planetary exploration rovers, automotive subsystems such as anti-lock braking systems and spin-assist, and every-day equipment such as autofocus cameras, video, hard disks, and CD players.

Are you ready for non combustion engines?
I'm very ready to go back no combustion age using another mode of transportation such as horses or by using the new solar powered energy...because the world now is getting hot.
What type of sleeve used for drill chuck used in lathe?
For drilling in a lathe, "Drill Sleeves" also known as "Drill Quills" are used and they are set into the tail stock quill for drilling operations.
What do engineers use coordinate planes for?
Because then would be able to figure out at what point would the window and the roof be at? And stuff like that.
Can you shut off an oil well by squeezing a pipe shut?
Yes, an oil well can be "shut off" by the use of a device that has a hydraulic ram that can crush and seal a pipe (or simply shut a valve) to secure a wellhead. The so-called "blowout preventer" is such a device, but in the case of the current disaster in the Gulf of Mexico, the device failed (owing to a failure to replace a battery, as one report had it).
Where can a DC exciter be found?
It can be found on an electrical generator set. It is used to supply the DC voltage for the field coils.
Why are panels of land-rovers made from aluminum?
Not being an automotive engineer, I can't say for certain, but aluminum has some very useful properties:
1. It does not rust beyond the outermost molecular layer, so water will not significantly weaken it.
2. It is very lightweight, important for gas mileage and such, especially with something as big as a land rover.
3. Unlike steel, it retains most of its strength even at freezing temperatures. At normal room temperature, steel is (by some measures) over 20 times stronger than aluminum. However, it quickly becomes more brittle as it chills, and will, at 0c, actually break more easily than an equivalent piece of aluminum. The aluminum also weakens as it chills, but much more gradually. Its effective strength at room temperature may not be much, but it's nearly the same at 0c. So you need more aluminum (and/or a stronger configuration) to hold up at room temperature, but you don't have to worry about it breaking in the cold.
(A lesson well illustrated by the WWII-era "Liberty Ships." Steel cargo ships which worked very well until they were brought through the chill temperatures of the northern Atlantic... at which point they snapped in half, one after another.)
4. It is also cheap, plentiful, easily molded, and readily recycled - all potential reasons to choose it over, say, carbon composite (which is also lightweight, strong, and rust-resistant).
5. It's shiny, or can be made so. People like shiny things.
I think it is also to do with availability. When the first Land Rovers were produced, just post WW2, there was lots of recycled aluminium around, from scrapped war planes. They were also, initially, an agricultural vehicle, so designed to have a long working life. This then became tradition at L/R, to have a lot of aluminium panels on their vehicles.
How do you get the level 60 gear in wizard101?
You can get your level 60 gear by going to blad raveneye in Triton avenue. If you are level 60 he will give you a quest to going in crab alley. You then follow the quests from the Herman in crab alley. The quest will come and the will ask you to enter the waterworks. This dungeon take 4 people.. The multiple bosses and fight will drop gear. You might not get your level 60 gear though.
"Edison failed 10, 000 times before he made the electriclight. Do not be discouraged if you fail a few times."
What is the abbreviation for circumference?
The abbreviation for circumference is a capital "C". Sometimes a "P" is used for perimeter.
Why is the letter W the widest letter?
Probably because it is made out of two letters (V) one next to each other.
Definition of scheduling in operating system?
the objective of multiprograming is to have some processs running at aal time,so as to maximizing cpu utillization .this process is called scheduling.
What technologies were developed in China during the Zhou dynasty?
For many centuries, Chinese farmers had to depend on rain to water their crops. Under Zhou kings, the Chinese developed new systems to irrigate the land. With a better water supply, farmers were able to grow more crops than ever before.
China's trade also expanded. Archaeologists have found pieces of Chinese silk in central Asia and as far away as Greece.
