The state of strain at the point has components of εx=-100(10-6), εy=-200(10-6), and γxy=100(10-6). use the strain-transformation equations to determine (a) the in-plane principal strains and (b)the maximum in-plane shear strain and average normal strain. in each case specify the orientation of the element and show how the strains deform the element within the x-y plane.

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.

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?
