Some physics students design an apparatus to measure the weight of objects using a beam and fulcrum pivot. One of the students stands on the apparatus to be weighed. The student, of weight w, stands .30m from end A of the uniform beam AB. The beam has a weight of 80N and length 2.om. A fulcrum pivot at P supports the blank and the downward loads and is .50m from end A. A counterweight of 70N is moved to the position 1.80m to balance the weight of the student and to put the system into rotational equilibrium. Determine the weight w of the student.

Air is to be preheated by hot exhaust gases in a cross-flow heat exchanger before it enters the furnace. air enters the heat exchanger at 95 kpa and 20°c at a rate of 0.6 m^3/s. the combustion gases (cp = 1.10 kj/kg°c) enter at 160°c at a rate of 0.95 kg/s and leave at 95°c. determine the rate of heat transfer to the air and its outlet temperature.
