Measure-while-drilling for ore characterisation: links between drilling and comminution properties of rocks The frequency of the peaks is connected to the rotary speed, the power and width are determined by the rock specimen, which indicates the peaks are a... Paredes Bujes,Constanza Ivonne 被引...
You can measure magnetic fields using instruments like gauss meters, and you can describe and explain them using numerous equations. Here are some of the basics: Magnetic lines of force, or flux, are measured in Webers (Wb). In electromagnetic systems, the flux relates to the current. A fie...
But it was delayed by the peculiar conditions Henry imposed on his engineers, so the Model A appeared with only four-cylinder power as an interim measure. Model A production ended in autumn 1931, though sales continued through April 1932. Then came a revised four-cylinder car, the Model B....
The Corolla seats up to five people, but if you have regular passengers at the back, the sedan version is preferred for more rear legroom. Meanwhile, the Corolla hatchback has the advantage of having 17.8 cu-ft of cargo volume. New in the 2021 Corolla is the ability to forgo the spare ...
Do you measure your rides in grins and smiles rather than seconds? If you’re into mountain biking uphill just as much as downhill and are looking for the occasional drop or jump, a trail bike is probably what you’re looking for. Trail bikes come with 27.5” or 29” wheels. ...
For relatively small swings, the time (T) it takes to make one complete swing (known as the period) is given by this little equation:Here, l is the length of the pendulum and g is a measure of gravity's strength (what we call the acceleration due to gravity). You can see from ...
Wind turbines have brakes to stop their rotors (propellers) turning too quickly. The brake is mounted inside the nacelle (the square-shaped casing behind the propeller that contains the gearbox and generator). Most turbines have an anemometer on them to measure the wind-speed. If the wind rise...
If you work with electronics and electrical systems, chances are very good you've heard about -- and likely own -- a multimeter. But to give the rest of us a little background, a multimeter is a handy device that's able to measure a wide range of parameters in the world of all thi...
Le/100 km is the Government of Canada equivalent measure of gasoline fuel efficiency for electric mode operation. Refer to "Specs" portion of applicable vehicle page for engine and transmission details. Actual fuel consumption will vary. 3. The Bluetooth word mark is a trademark of the Blu...
On top of that, while petrol-electric hybrid and pure electric drivetrains are making cars far cheaper to run, exactly how efficient they are compared to ‘traditional’ petrol and diesel cars can be difficult to measure. We’re going to help you overcome that now, though. We tend to ...
