Consider the double shear lap joint, which is glued to a clevis. compute the shearing stress in the adhesive, if the width of the splice is 4 inches. 3b) what is the shearing stress in the bolts, if there are two bolts equally loaded in the joint. the bolt diameters are 1/2". 3c) what is the bearing stress on the splice plate? 0.5" 250 [lb]

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.
