I Would Icarus' wings fly in Earth's atmosphere and moon gravity?

AI Thread Summary
The discussion centers on the feasibility of Icarus' wings generating enough lift in Earth's atmosphere and lunar gravity. Participants question the specific weight ratio of 1/11th a human's weight, noting that lunar gravity is actually 1/6th. The conversation highlights the challenges of determining lift without a defined wing design and references the melting point of materials used in the myth. Comparisons are made to real birds, like the wandering albatross, to assess potential wing dimensions. Ultimately, the thread suggests a shift towards exploring optimized human-powered flight rather than focusing solely on the mythological aspect.

Could they generate enough lift for 1/11th the weight of a human? Was picturing a giant warehouse and curious if it would work!

:oldconfused: Why 1/11th? Lunar gravity is 1/6.

Practically, there's no way to really know. How do you decide how much lift a human could produce without first choosing or designing the wings?
 
We have the legend of Icarus flying in the atmosphere.
The problem then was the melting point of the bee's wax used to attach the feathers.
 
Oh my goodness - 1/6th thanks Dave! Bit of a spaceshot here haha. Thats a good point.
 
A wandering albatross weighs around 25 lbs and has a 10 ft wingspan so the dimensions would not be unreasonable.

Since this thread start is in the technical Physics forms and not SciFi, shouldn't you be asking about how much farther optimized human powered flight could fly?

Thread 'Gauss' law seems to imply instantaneous electric field propagation'
Imagine a charged sphere at the origin connected through an open switch to a vertical grounded wire. We wish to find an expression for the horizontal component of the electric field at a distance ##\mathbf{r}## from the sphere as it discharges. By using the Lorenz gauge condition: $$\nabla \cdot \mathbf{A} + \frac{1}{c^2}\frac{\partial \phi}{\partial t}=0\tag{1}$$ we find the following retarded solutions to the Maxwell equations If we assume that...
Dear all, in an encounter of an infamous claim by Gerlich and Tscheuschner that the Greenhouse effect is inconsistent with the 2nd law of thermodynamics I came to a simple thought experiment which I wanted to share with you to check my understanding and brush up my knowledge. The thought experiment I tried to calculate through is as follows. I have a sphere (1) with radius ##r##, acting like a black body at a temperature of exactly ##T_1 = 500 K##. With Stefan-Boltzmann you can calculate...
Thread 'Griffith, Electrodynamics, 4th Edition, Example 4.8. (First part)'
I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8 and stuck at some statements. It's little bit confused. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. Solution : The surface bound charge on the ##xy## plane is of opposite sign to ##q##, so the force will be...
