Aperson drops a cylindrical steel bar ( =1.100×1011 pa ) from a height of 4.60 m (distance between the floor and the bottom of the vertically oriented bar). the bar, of length =0.820 m , radius =0.00550 m , and mass m=1.200 kg , hits the floor and bounces up, maintaining its vertical orientation. assuming the collision with the floor is elastic, and that no rotation occurs, what is the maximum compression of the bar?

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

Water vapor initially at 10 bar and 400 °c is contained within a piston-cylinder assembly. the water lost heat to the surrounding according to isochoric (iso-volumetric) process until its temperature is 150 °c. the water is then condensed isothermally to saturated liquid. for the water as a system, calculate the work in kj/kg
