What increases wing area to produce lift? Increasing the airspeed will increase the lift. Increasing the camber will increase the lift. A symmetric airfoil, or even a flat plate at angle of attack, will generate lift. Lift appears to be a very strong function of the airfoil camber. How a wing creates lift? How Wings…

Why is magnesium HCP?
Why is magnesium HCP? Firstly, magnesium is an alkaline earth metal, not a alkali metal. And secondly, magnesium is not unique within the alkaline earth metals in having a hexagonal close-packed crystal structure… beryllium also has a HCP structure. Is magnesium a HCP? Magnesium is hcp with c/a =1.624, density = 1.74g/cm^3. Which electron’s do…
Why do similar matrices have different eigenvectors?
Why do similar matrices have different eigenvectors? If A and B are similar matrices, then they represent the same linear transformation T, albeit written in different bases. So really the two matrices have the same eigenvectors, they just look different because you’re expressing them in terms of a different basis. Can eigenvectors be the same?…
Why do I hear beeping in my wall?
Why do I hear beeping in my wall? Some are innocuous- the battery in some electronic device or toy may be dying. There are also beeps that can signal danger, a smoke alarm, a CO2 alarm, a water sensor, and many more. If you are not old enough to check it out yourself, leave the…

How do you find the North Star in the southern hemisphere?
How do you find the North Star in the southern hemisphere? At the equator, Polaris would appear to sit right on the horizon. So if you travel to the north, the North Star climbs progressively higher the farther north you go. When you head south, the star drops lower and ultimately disappears once you cross…
Can 3×3 matrix have 4 eigenvectors?
Can 3×3 matrix have 4 eigenvectors? So it’s not possible for a 3 x 3 matrix to have four eigenvalues, right? right. How do you find eigenvalues and determinants? det(A) = λ1 · λ2 ····· λn i.e. the determinant is the product of the eigenvalues, counted with multiplicity. Show that the trace is the sum…
How do ADHD and autism relate?
How do ADHD and autism relate? In a 2014 review of studies looking at the co-occurrence of ADHD and ASD, researchers found that between 30 to 50 percent of people with ASD also have symptoms of ADHD. Researchers don’t fully understand the cause for either condition, or why they occur together so frequently. Both conditions…
