H.W 4: The beam shown below is subjected to the distributed loading of w=120 kN/m. Determine the principal stresses in the beam at point P, which lies at the top of the web. Neglect the size of the fillets and stress concentrations at this point. I=67.4×10-6 m4. 15 mm w=120 kN/m B 0.3 m 2 200 mm A 10 rim 15 mm 175 mm
A 3 m x 5 m section of wall of the cold room is not insulated, and the temperature at the outer surface of this section is measured to be 7°C. The temperature of the outside room is 30°C, and the combined convection and radiation heat transfer coefficient at the surface of the outer wall is 10 W/m2°C. It is proposed to insulate this section of the furnace wall with glass wool insulation (k = 0.038 W/m°C) in order to reduce the heat transfer by 90%. Assuming the outer surface temperature of the cold room wall section still remains at about 7°C, determine the thickness of the insulation that needs to be used.
