The displacement volume of an internal combustion engine is 5.6 liters. the processes within each cylinder of the engine are modeled as an air-standard diesel cycle with a cutoff ratio of 2.1. the state of the air at the beginning of compression is fixed by p1 = 95 kpa, t1 = 27°c, and v1 = 6.0 liters. determine (a) the net work per cycle, in kj, (b) the power developed by the engine, in kw, if the cycle is executed 1500 times per min (c) the thermal efficiency.

Afoot bridge is made as a simple deck, 4 m long, with a cross section 2 m (wide) and 20 cm thick, and made of wood. the deck is supported at the two ends. the maximum load allowable on the bridge is 10 tons, provided it is uniformly distributed on the deck. to sense this load, a strain gauge is placed at the center of the bridge and its resistance is monitored. if the sensor has a nominal resistance of 350 s2 and a gauge factor of 3.6, what is the reading of the strain gauge at maximum load? the modulus of elasticity for the wood used in the construction is 10 gpa.
