A10-in. length of steel tubing (with properties of e =30 x 10^6psi v=0.3 and α=7x10^-6/ f° and q. cross-sectional area of 1 square in is installed with fixed ends so psi, v having that it is stress-free at 80°f. in operation, the tube is heated throughout to a uniform 480°f careful measurements indicate that the fixed ends separate by 0.008 in. what loads are exerted on the ends of the tube, what are the resultant stresses and strains?

On a average work day more than work place firs are reorted

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
