Question
A two-dimensional rectangular plate is subjected
to prescribed boundary conditions, T1 = 50°C,
T2 = 140°C. The temperature distribution
equation, derived by applying separation of
variable methods to a two-dimensional conduction
problem for a thin rectangular plate or long
rectangular rod, is as follows.
