The top of a 30-cm I-beam is maintained at a temperature of 260ºC, while the bottom is at 93ºC. The thickness of the web is 1.25 cm. Air at 260ºC is blowing along the side of the beam so that h̅ = 40 W/ (m² K). The thermal conductivity of the steel may be assumed constant and equal to 43 W/(m K). Find the temperature distribution along the web from top to bottom and plot the results.
