Afour-cylinder, four-stroke internal combustion engine has a bore of 3.7 in and a stroke of 3.4 in. the clearance volume is 16% of the cylinder volume at bottom dead center and the crankshaft rotates at 2400 rpm. the processes within each cylinder are modeled as an air-standard otto cycle with a pressure of 14.5 lbf/in.2 and a temperature of 60f at the beginning of compression. the maximum temperature in the cycle is 5200r. based on this model, calculate the net work per cycle, in btu, and the power developed by the engine, in horsepower.

Water at 55c flows across a flat plate whose surface temperature is held constant at 95c. if the temperature gradient at the plate's surface for a given value of x is 18 c/mm, find a) local heat transfer coefficient. b) heat flux

Modern high speed trains do not have perpendicular expansion gaps where rails are joined end-to-end any more they are mostly welded together but what might happen if there was a spell of particularly hot weather that causes inspection of the tracks?

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.
