PHYSICS 312
PROBLEM SET 2:
Given January 15. Due January 22. 1999.
Problem 1:
Heat is produced uniformly at the rate H (energy per time per volume)
inside a sphere of radius c. The thermal conductivity of the sphere is
.
At the surface of the sphere heat loss per unit surface area to the surroundings is
Find the steady state temperature
at radius
inside the sphere.
Problem 2:
A large object has a spherical hole of radius c.The thermal conductivity of the object is
.
At the surface of the hole the temperature is 0. Far away from the
hole the temperature is T. Find the steady state temperature
at a distance r>c from the center of the hole.
Problem 3:
The function f(x) is defined for
as
Find the Fourier series for the
- a:
- periodic extension (use either the sine/cosine or complex series)
- b:
- even periodic extension
- c:
- odd periodic extension.
