The deflection of a uniform beam subject to a linearly increasing distributed load can be computed as 120 E I L (−x5 + 2L2x3 − L4x) Given that L = 600 cm, E = 50,000 kN/cm2, I = 30,000 cm4, and 0 = 2.5 kN/cm, determine the point of maximum deflection (a) graphically, (b) using the golden-section search until the approximate error falls below εs = 1% with initial guesses of xl = 0 and xu = L.

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

For the closed feedwater heater below, feedwater enters state 3 at a pressure of 2000 psia and temperature of 420 °f at a rate of ix10 ibhr. the feedwat extracted steam enters state 1 at a pressure of 1000 psia and enthalpy of 1500 btu/lbm. the extracted er leaves at an enthalpy of 528.7 btu/lbm steam leaves as a saturated liquid. (16) a) determine the mass flow rate of the extraction steam used to heat the feedwater (10) b) determine the terminal temperature difference of the closed feedwater heater
