Design the vertical alignment (i. e., the sag curve followed by a constant grade connection, followed by a crest curve). Assume that we are provided with the elevation of Point I as 34.5 ft. Note, if the calculated curve lengths are too short, please pick reasonable values for them and justify your choices. The following information required as part of the Vertical Curve Point Elevation (ft) Station 1 PVC (A) 16 13 45 PVI PVT 2 PVC PVI PVT (I) 28 42 G1sag G2sag Length of sag curve Gconn Length of connection G1 Crest G2 Crest Length of crest curve

Asimple rankine cycle uses water as the working fluid. the water enters the turbine at 10 mpa and 480c while the condenser operates at 6 kpa. if the turbine has an isentropic efficiency of 80 percent while the pump has an isentropic efficiency of 70 percent determine 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.

When subject to a steady load (within elastic range) over a long period of time, what is the major difference in material behavoir between steel and plastic?
