Q4
(a)
The temperature distribution u(x, t) of the one-dimensional gold rod is governed by
the heat equation as follows.
a²u
ди
= 0.25-
at
ax2
Given the boundary conditions u(0, t) = 2t?, u(1, t) = 5t, for 0 <t < 0.04 s and
the initial condition u(x,0) = x(1 – x) for 0<x< 1.0 mm, analyze the
temperature distribution of the rod with Ax = 0.25 mm and At = 0.02 sin 4 decimal
places.
