Greek Mythology! Great stories, with great twists and many awkward and hardcore stuff that make Game of Thrones look like a Family sitcom.
One of the great stories is the one with the Gigantomachy. Long story-short, some Giants gathered and thought that it would be a great idea, to fight the Greek Gods and take the control of Cosmos (the world). A lot of epic battles occurred in this fight, and one of the greatest is between Athena and Enceladus.
Enceladus, who has NO known connection to enchiladas, was the offspring of Gaia, born from the blood that fell when Cronus castrated his father, Uranus (awwwwkwaaaard!). There is another version of the story where he was just the son of Tartartus and Gaia, but we prefer the other one.
Well, he and Athena fought and she beat him with her spear, and then burried him under the mount Etna in Sicily.
The volcanic fires of Etna were said to be the breath of Enceladus, and its tremors to be caused by him rolling his injured side beneath the mountain. In modern Greece, an earthquake is still often called a “strike of Enceladus”.
But let’s face it. The attempt to take over Olympus and the world against Gods, was pretty lame!
A Lame attempt for World Domination PLUS a guy who is responsible for earthquakes?
Enceladus= Earthquakes , Earthquakes + Lame = X
BUT OFCOURSE! It reminds me “Lame’s first parameter”!
X= Lame’s 1st Parameter!!
Earthquakes + Lame = Lame’s 1st Parameter <=> Lame = Lame’s 1st Parameter – Earthquake
In linear elasticity, the Lame parameters are the two parameters that constitute a parametrization of the elastic moduli for homogeneous isotopic media. The first parameter is related to the bulk modulus( the modulus of in-compressibility) and the shear modulus (modulus of rigidity) in three dimensions.
In our database you can find Lame’s first parameter – for 2D solids, which is given by the equation on the left.
λ is Lame’s first parameter in 2D (Pa), K the bulk modulus which is always greater than Zero (K>0) (Pa) and μ is the Shear modulus, also denoted as G (Pa).
Lame’s first parameter is slightly changed for three dimensions. The formula is this one on the left.
It also has a direct connection to P-Wave Velocity, which is about seismic waves velocity. But we will tell you more about that in our next post.
Go ahead, check this equation and search whatever else you want to solve. You will find some help in our fxSolver video.

*Disclaimer: We don’t imply that there is anything “lame” in Lame’s formulas. It is just a combination of word-play with some equation humor!
