1 hr = 3600 sec
→ 21000 mph = 21000 ÷ 3600 mps = 5 5/6 mps → 6 mps to the nearest mps.

Which costs more aluminum or steel?
For homework: Aluminum is about 7 times more expensive than steel. A full answer: Basically: Aluminum is more expensive. And during 2011 is expected to go higher, because of less demand. Although the price of steel is constantly on the raise. BUT, in some cases making things from steel can turn out to be more expensive. Like boats. But again, in the usual case Aluminum is more expensive. How much more expensive depends: There are different kinds of steel. Also, it depends on how much material you'll need. Sometimes a small amount of aluminum will suffice for a much larger amount (in weight) of steel you would need for the same task. In that case making your project from aluminum will cost less than from steel. But the raw cost of steel is still cheaper than that of aluminum. (The reason is that aluminum, although more "abundant" - meaning found more on the surface of earth, is harder and therefore more expensive to retrieve). The most significant cost difference, is the cost of work: tools, knowledge and the price for fixing mistakes. Working with aluminum is much more expensive than steel. In 2002 (before the price rise of steel) it was 4.2 times more expensive to make a car from aluminum, than from steel. But then a comparison by a boat maker shows that its EASIER to work with aluminum, if you use its features to your advantage: (No need to paint submerged parts, build without bending, use standard profiles etc.) and easier to sell. And then it depends if you need to use new material or can use scrap. Today (March 2011) iron ore (the main part for making steel) is 4 and a half cents per pound, while aluminum is a dollar and 14 cents! 0.045 vs 1.14. That's Aluminum over 25 times more expensive than iron. (But then again, steel is about 3.5 times more expensive than iron, so aluminum is about 7.2 times more expensive now. Please understand that a shortage (like the one during the Chinese Olympics a few years ago) can make the price of steel rocket up, and change everything. So you never know what will be. But currently, Aluminum is more expensive. By the way, Mary Antoinette had a set of cutlery (knife, fork and spoons) from aluminum, that was at that time just discovered, and more expensive than silver.
How do you operate a hi tec burning log turbo 10 fire?
If it is the older style with a long rather than wide firebox, and tiles along the side, then the following should get you started. It may also be relevant to later models ... The lever above the door that moves sideways controls the damper at the rear of the firebox, which has to be to the right (opens the damper and moves an interlock metal tab to the right) to allow the door to be opened. The small lever at the top front on the right hand side sets the air intake in 3 steps, to the rear for maximum air, to the front for minimum. When the damper opens the interlock mentioned above should pop the intake lever back to maximum. I have experienced 2 well used units, and the damper lever linkages on both have been in bad shape. This means to close the damper (lever to left) properly may require a bit of technique, see below. To start, damper lever to right, open door; my technique is to feed in plenty of screwed up paper, then a layer of twigs or kindling, then a couple of decent bits of timber on top. At the very last, a few screwed up sheets of newspaper at the very front filling up the door, gets everything happening fast. Light this newspaper in a couple of places, then immediately almost fully close the door, leaving it ajar about 3cms of so. The fire should take off like a rocket; move the door in or out to adjust how ferocious it is. What you want is for the chimney at the base to get pretty hot, and to see that decent pieces of timber are well and truly burning. Then close the door properly, using the lever; don't over-tighten as the catch is a bit flimsy and will bend if you overdo it. At this point the damper is open, air intake is maximum. As soon as the fire appears to be really stable close the damper, which may need some fiddling -- to do this, move the lever to the left, then slide the interlock tab with your finger to the left, then move the lever again to the left with a bit of a jerk. When the damper closes properly it will make a bit of a clang; if your unit has this problem you'll probably have to experiment a bit to get the technique right. If the fire dies down at this point you've been too eager to close the damper: damper lever to right, open the door a touch to get it going once more, and try again. With the damper closed the wood is being burnt in the most efficient way, giving off the most heat for the wood used; the only thing to worry about then is the air intake. Lever to the back for maximum heat, towards the front slows the burning rate, and if you fill the firebox last thing at night the front setting should give you a still usable fire in the morning! Depending upon the type of wood burning and the air intake setting, you need to be careful opening the door: do it too quickly and you will have smoke pouring out into the room! Only open it a few cms or so initially, and leave the fire to stabilise a bit before opening further. This is also the way to get the fire going again if it suffocates (firebox fills with smoke) Good luck! Frank
What tool is used to mark lines at right angles?
Names of Tools Used to Measure AnglesPrint this articleWhile many may think of angles only in terms of geometry, angles occur in most everything. We recline our car seat to a comfortable angle. We adjust our computer monitors to angle them so we can see the screen easier. Architecture uses more than 90-degree angles; it also uses other aesthetic angles to create more interesting buildings. Art uses angles in all media. Angles can be used to calculate heights and locations. Angles are everywhere. As such, we have special instruments to measure angles.The ProtractorThe protractor is the most basic tool for measuring angles. It is used in math applications from engineering to architecture. The most common protractor is a half-circle with degrees marked from 0 to 180. Most protractors mark degrees in both directions, creating a double row of numbers. So it is important to assess whether the angle is smaller or larger than 90 degrees (a right angle) before deciding which row of numbers to use. Full circle, round protractors can also be found, which will be marked up to 360 degrees. Bevel Protractors have swinging arms to help measure the angle. Because these types of protractors have moving parts, they are classified as mechanical protractors.Navigational PlotterAviators use a navigational plotter to help plot their course. A typical navigational plotter looks much like an ordinary plotter attached to the top of a ruler. A fixed plotter has the half-circle protractor directly over the ruler, while a rotating plotter uses a circle (or round) protractor attached to the ruler. Because aviators use both statue (standard) miles and nautical miles for their measurements, plotters typically have both scales on them. The pilot places the hole in the protractor base of the plotter over a longitude line and then angles the ruler along the flight course marked on a sectional. The pilot can read the true course where the longitude line intersects the protractor (or plotter's azimuth).The SextantSextant is Latin for one sixth. The instrument's scale measures 60 degrees, or one sixth of a circle. Sextants have been used by navigators at sea for centuries. The instrument measures the altitude of a celestial object, such as the sun, above the horizon. Navigators use this angle along with the time of day (or night) to calculate their position line on a nautical chart. Commonly, sailors calculated their latitude by sighting (measuring with the sextant) the sun at noon. The sextant could also be laid on its side and used horizontally against charts to measure angles, such as the angle between two objects. Using it this way, navigators were able to calculate their position.The TheodoliteA theodolite is a field instrument used by surveyors, generally set up on a tripod for stability. It is composed of a movable telescope mounted within two axes, a horizontal axis and a perpendicular vertical axis. They are used to determine line of sight and for measuring the angles between survey marks. They accurately measure both vertical and horizontal angles down to arc seconds and are particularly useful when measuring inaccessible ground. While theodolites are key for engineering and surveying, they have also been adapted for use by other fields, such as meteorology and rocket launch technology.Miter SawBuilders use the miter saw (also spelled "mitre" saw) for making angled cuts in wood. Because the saw's angle-measuring component resembles a box, the saw is also called a miter box. The wood is held against a straight piece, called the fence. The miter saw's blade (usually a circular blade) cuts at an angle to the fence, making a vertical cut. This angle can be adjusted by one degree increments. There are usually "stops" built into the box at commonly cut angles, such as 45 degrees. At the standard position, the miter saw makes a 90 degree cut. A compound miter saw also allows for angle changes to be made in cutting on the horizontal plane. This can be used to make beveled cuts. A slide allows the saw to make cuts longer than the blade's diameter. When the latter two features are combined, the saw is called a sliding compound miter saw.
