A425-lb engine is suspended from a vertical chain at a. a second chain is wrapped around the and held in position by the spreader bar bc. determine the compressive force acting along the axis of the bar and the tension forces in segments ba and ca of the chain. hint: analyze at equilibrium first at a then at b.

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?

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

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.
