Awater tank is completely filled with liquid water at 20 degree celcius. the tank material is such that it can withsatand tension caused by a volume expansion of 2%. determine the max temperature rise in celcius degress allowed without jeopardizing safety. neglet the effect of pressure change.

Fluids at rest possess no flow energy. a)- true b)- false

Thermal stresses are developed in a metal when its a) initial temperature is changed b) final temperature is changed c) density is changed d) thermal deformation is prevented e) expansion is prevented f) contraction is prevented

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
