Many of these entities have been given simple and ambiguous names such as Euler's function, Euler's equation
, and Euler's formula.
The latter requires application of Euler's equation
from the calculus of variations.
When L is [greater than or equal to] 400 mm, [[sigma].sub.b] obtained by Southwell's method and Engesser's tangent modulus are close to that predicted by Euler's equation
. For small L, however, [[sigma].sub.b] obtained by Southwell's method is smaller than that predicted by Euler's equation
The load carrying capacity of a regular circular column is given by Euler's equation
The simplest estimate, using Euler's equation
for the buckling force on a beam (8), the bending stiffness of a single microtubule decorated with associated proteins [~5 x [10.sup.-23] [Nm.sup.2]] (9), the average number of microtubules of a newt lung kinetochore [~20] (5), and the average measured length of the kinetochore fiber [~10 [mu]], predicts that the buckling force on a 10-[mu]-long and growing kinetochore fiber would be 100 pN!
He converted the problem into an equivalent mathematical form that enabled him to pick out candidates likely to satisfy Euler's equation
. A few other mathematicians had tried a similar approach, says Elkies, but either they gave up too soon or they were thinking in terms of proving rather than disproving the conjecture.
Here, the authors complete the proof of the envelope theorem for the class of variational problems concerned, using the corresponding Euler's equation
He then moves to applications in Fourier series, including strings and springs, and devotes the rest of the text to the calculus of variations, including Euler's Equation
, harmonic functions, Hamilton's Action and Lagranges' Equation, finishing with nonEuclidean geometry and some fun with relativity.
Shape optimization of fibers in a composite structure presented in this paper is based on an original formulation of optimal shape problems leading to Euler's equations
belonging to the optimization.
The classes of offshore structures are described in a short introduction, followed by a review of fundamental equations and concepts of motion, rotational and irrotational flows, velocity potential, Euler's equations
, steam function and other concepts.
