The state of stress at a point is given by σxx = 65 MPa, σyy = -49 MPa, σzz = 38 MPa, σxy = 28 MPa, σyz = 0 MPa, and σzx = 0 MPa. Calculate the sum of the three principal stresses. Provide your answer in MPa (you do not need to type the units).

Inadequate stores control is not an obstacle to effective work order system. (clo4) a)-true b)-false

Apiston-cylinder device contains 0.1 m3 of liquid water and 0.9 m3 of water vapor in equilibrium at 800 kpa. heat is transferred at constant pressure until the temperature of water reaches 350 °c. determine (a) the quality of water at the initial state (b) the work associated with this process, (c) the heat associated with this process.
