To calculate the normal and shear stresses at a point in a beam subjected to a combined loading. the state of stress at a point is a description of the normal and shear stresses at that point. when a structural element is subjected to multiple kinds of loads, the effects of each can be combined using the principle of superposition, as long as the deflections remain small, the response is elastic, and the material is homogenous. the beam shown (figure 1) is supported by a pin at a and a cable at b. two loads p = 20 kn are applied straight down from the centerline of the bottom face. determine the state of stress at the point shown (figure 2) in a section 2 m from the wall. the dimensions are w = 4.6 cm , h = 11.5 cm , l = 0.8 m , a = 1.5 cm , and b = 4 cm .

Along 8-cm diameter steam pipe whose external surface temperature is 900c connects two buildings. the pipe is exposed to ambient air at 70c with a wind speed of 50 km/hr blowing across the pipe. determine the heat loss from the pipe per unit length. (b) air at 500c enters a section of a rectangular duct (15 cm x 20 cm) at an average velocity of 7 m/s. if the walls of the duct are maintained at 100c. a) the length of the tube for an exit temperature of the air to be 40 0c. b)the rate of heat transfer from the air. c) the fan power needed to overcome the pressure drop in this section of the duct.
