Consider a bone-like sample cut into a long rectangular prism that has a healing fracture that forms an angle of 60o with the shaft. when the sample is loaded in compression equivalent to half of the person’s weight, what is the stress in the sample normal to a transverse cross-section of the shaft and normal to the healing fracture? for simplicity, assume external loading forces are only in-line with the solid shaft. body mass = 60 kg, g=10 m/s2 , cross-sectional area of shaft a=4 cm2

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.
