The following is a physics question i have no idea how to do, please help:?

Question

The Write Brothers Flyer has a take-off weight of 750 lb and wing area of 47 m2. Determine the velocity of Flyer using the equation for wing loading.

Answer 1

In aerodynamics, wing loading is the loaded weight of the aircraft divided by the area of the wing.[1] It is broadly reflective of the aircraft's lift-to-mass ratio, which affects its rate of climb, load-carrying ability, and turn performance.

In physics, velocity is defined as the rate of change of position.

Did you want vertical velocity (rate of climb)?

Answer 2

it can not be done

you can not get any velocity from that info but the wing loading is 15.9574lbs/m2    as in     750divided by47

just divide the mass of the aircraft by the wing surface area for the wing loading

Answer 3

What is the equation?

Answer 5

Here is a web site that offers an equation you can solve, if you can estimate the coefficient of lift and the air density:

The coefficient of lift is a function of wing geometry and its orientation with respect to the direction of flight. Air density depends mostly on altitude and temperature. You can probably assume standard temperature and pressure at sea level, since the Wright brothers flew their prototype for the first time near the Atlantic ocean instead of at their home town, Dayton, Ohio. I have no idea what the coefficient of lift would be. You can probably get a fair estimate by assuming the Wright Flyer was moving at a maximum speed of no more than 30 mph during its brief intial flight, but then that's the answer you are looking for in the first place.

As for "the equation" you can't seem to find, that would probably be Bernoulli's Equation. However, it is a gross over-simplification to say that equation "explains" how a wing works. See also this site:

Answer 6

The limiting speeds of an airframe are determined by a number of factors you have not been given.  You need to talk to your teacher and let him/her know the problem is not set up correctly.
