Q5*) Write down an immediate first integral for the Euler-Lagrange equation for the integral
I =
= F(x, y, y″) dx.
Hence write down a first integral of the Euler-Lagrange equation for the integral
I
1 = √(xy ² + x³y²)
dx.
Find the general solution of this ordinary differential equation, seeking first the complementary function and
then the particular integral. (Hint: the ODE is of homogeneous degree. And, for the particular integral, try
functions proportional to log x.)
Q2*) In question P3 we showed that a minimal surface of revolution is given by revolution (about the x-axis)
of the catenary, with equation y = C cosh ((x – B)/C).
-
(a) Suppose, without loss of generality, that the catenary passes through the initial point
P = (x1,y1) = (0, 1). First deduce an expression for the one-parameter family of catenaries passing
through point P. Next calculate the value of x at which y takes its minimum value. By using the inequality
cosh > √2
(you might like to think about how to prove this), show that there are points Q for which it is impossible to find
a catenary passing through both P and Q. In particular, show that it is impossible to find a catenary joining
the points (0, 1) and (2, 1).
(b) A minimal surface of revolution can be realised experimentally by soap films attached to circular wire
frames (see this link and this link for examples). The physical reason for this is that the surface tension, which
is proportional to the area, is being minimised.…
Q3*) Consider the integral
I
Yn, Y₁, Y2, . . ., Y'n) dã,
[F(x, Y 1, Y2, · · Yng)
= -
where y1, 2, ...y are dependent variables, dependent on x. If F is not explicitly dependent on x, deduce
the equivalent of the Beltrami identity. Optional: Give an example of a function F(y1, Y2, Y₁, y2), and write
down the Euler-Lagrange equations and Beltrami Identity for your example. Does having this Beltrami Identity
help solve the problem?
