A 6 ft high column is made from a hollow steel shell filled with concrete. The steel shell cross-section is 6 in x 6 in square with a wall thickness of 1⁄2 in. The column is subjected to a load of 1,000 kips. ES = 29x106 psi, and EC = 3.5x106 psi. a. Calculate the load supported by the steel and by the concrete. b. Calculate the stress in the steel and the stress in the concrete. c. Calculate the deflection of the column.

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
