maximum principal stress in a beam of this profile when the beam
has the loading and location of loading shown below. the allowable
normal stress is 400 mpa and the allowable shear stress is 100
mpa.

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.
