Afour stroke gasoline engine has a compression ratio of 10: 1 with 4 cylinders of total displacement 4.2 l. the inlet state is 290 k, 80 kpa and the engine is running at 3200 rpm with the fuel adding 1400 kj/kg in the combustion process. what is the network in the cycle and how much power is produced?

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.
