Four cables are tied to a frictionless ring at A and tied to fixed supports a B, C, D, and E. Knowing that a 220-lb vertical load P is applied to ring A and that the tension in AB is 71.1 lbs, determine the tensions in the other 3 cables.

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)

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

Burgers vector is generally parallel to the dislocation line. a)-true b)-false
