Calculate the normal strain in the steel bar given below when 10.0 kips10.0 kips is applied. The bar is 2 inches in diameter and 20 inches long before the load is applied. E=29000 ksi. E=29000 ksi. (Note: a micron is 10−6 in./in.10−6 in./in.

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

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.
