Question: Assume that node m in Problem 3-39 occurs along a circular rod having a diameter of 2 cm with x = 1 cm. The material

Assume that node m in Problem 3-39 occurs along a circular rod having a diameter of 2 cm with ∆x = 1 cm. The material is glass with k = 0.8 W/m· ºC, ρ = 2700 kg/m3, c = 0.84 kJ/kg · ºC. The convection surrounding condition is h = 50W/m2 · ºC and T∞ = 35ºC. Write the transient nodal equation for node m and determine the corresponding maximum allowable time increment, expressed in seconds.
