Imagine you were hired by an insurance company to determine the agma rating of a pinion in a failed gearbox. the pinion is cut to a pressure angle of 20°, has 17 teeth and its module is 12 mm. the operating speed is 2000 rpm. your calculations reveal that, for this pinion material, bending failure should be expected if the tangential force exceeds 4200 n and pitting failure should be expected if the tangential force exceed 3529 n. what should your report to your customer say about the maximum power that can be transmitted under these conditions without including a factor of safety? (a)24 kw (b) 75 kw (c) 119 kw (d) 48 kw

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.
