So why does the M-1 tank use a 1,500 horsepower gas turbine engine instead of a diesel engine? It turns out that there are two big advantages of the turbine over the diesel: Gas turbine engines have a great power-to-weight ratio compared to reciprocating engines. That is, the amou...
Figure 6. The ignition system HowStuffWorks Theignition system(Figure 6) produces a high-voltage electrical charge and transmits it to the spark plugs viaignition wires. The charge first flows to adistributor, which you can easily find under the hood of most cars. The distributor has one wire...
In addition, these tunnels can help engineers figure out how wind interacts with stationary objects, such as buildings and bridges, and find ways to make them stronger and safer. In short, many of our modern marvels are more advanced thanks to wind tunnels. But it was the dream of flight ...
Many manufacturers of large diesel engines therefore use this approach to create high-power engines. The figure shows the layout of a typical two-stroke diesel engine: At the top of the cylinder are typically two or four exhaust valves that all open at the same time. There is also the ...
For this step, you’ll need to “get in the shoes” of your website visitors. Try to figure out where they go when they stumble upon a problem (for which you offer a solution), how they speak (like the terms and phrases they use) in that niche, etc. ...
Choose a web hosting plan that holds up to your requirements, depending on the scale and type of site you want to run. Shared or WordPress hosting can be a good starting point if your website doesn’t require much server horsepower just yet. Make sure to explore the features of each ...
To reverse the direction of rotation To increase or decrease the speed of rotation To move rotational motion to a different axis To keep the rotation of two axes synchronized You can see effects 1, 2 and 3 in the figure above. In this figure, you can see that the two gears are rotating...
For a while,NASAeven had a research program to figure out how to make it super-easy for ordinary folks to use this little-known network by flying on it themselves. But one of the key elements would be small, relatively affordable planes that were as easy to operate as cars [source:NASA...
To calculate your vehicle’s maximum capable tongue weight, compare your gross vehicle weight to your vehicle’s weight when it’s fully loaded. What if you want to figure out how much weight your trailer tongue adds to your truck? Then take your truck and your trailer to the local weigh...
Check whether or not you really need to convert. For example, if you started with a bhp figure from an auto magazine and you want mechanical horsepower, you don't need to convert. If you do need to convert, find one of the many Internet sites that will convert between the two different...
