Find the temperature function u(x,t)u(x,t) (where xx is the
position along the rod in cm and tt is the time) of a 1818 cm rod
with conducting constant 0.10.1 whose endpoint are insulated such
that no heat is lost, and whose initial temperature distribution is
given by:
u(x,0)={5 if 6≤x≤12
{0 otherwise
To start, we have L=18 0.1 Because the rods are insulated, we will use the cosine Fourier expansion. 22 Ac + =1 A cos(" )e| A cos( u(x,...

Problem 6 Find the temperature in in a laterally insulated bar of length L whose ends are also insulated, assuming the same initial temperature profile as in Problem 5. Hint: remember that if the end points are thermally insulated, there is no heat flow. Hence, the temperature gradient must vanish at the endpoints! Problem 5 Find the temperature in a laterally insulated bar of length whose ends are kept at 0° Celsius, assuming that the initial temperature distribution is in...
