Question

In a matrerial the principal stress are 60 ,48,36.Find total strain energy per unit volume

Answer 1

2–8 consider a river flowing toward a lake at an average velocity of 3 m/s at a rate of 500 m3/s at a location 90 m above the lake surface. Determine the total mechanical energy of the river water per unit mass and the power generation potential of the entire river at that location.
