In most finite element results, we can display stresses as any of the components, principals, or as the equivalent stress. In most basic mechanics texts, equivalent stress is calculated only after principal stresses are determined. Is this necessary? A few basic questions to answer this question.1.Write the equations to determine the three principal stresses given a general, three-dimensional stress state.2.Write the equation to determine the von Mises equivalent stress (Distorion Energy) given a general, three-dimension stress state and also the eqation given the three principal stresses.3.When viewing finite element results, which states of stress should you consider: 1) component stress, 2) principal stress or 3) equivalent stress? There may be more than one answer; if so, you need to describe when each is recommended.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200Β°c and outer surface temperature of the insulation to be 15Β°c. calculate the thickness of insulation required.
