A specimen of a ceramic material having an elastic modulus of 250 GPa is pulled in tension with a stress of 750 MPa. Will the specimen fail if its ""most severe flaw"" is an internal crack that has a length of 0.20 mm and a tip radius of curvature of 0.001 mm? Why or why not?

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

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?

A-mn has a cubic structure with a0 0.8931 nm and a density of 7.47 g/cm3. b-mn has a different cubic structure, with a0 0.6326 nm and a density of 7.26 g/cm3. the atomic weight of manganese is 54.938 g/mol and the atomic radius is 0.112 nm. determine the percent volume change that would occur if a-mn transforms to b-mn.
