Mining engineers rely on which of the following to provide enough data to predict the possible effects of and prescribe optimal solutions for their designs

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.

Two slings are used to lift a girder of length l and uniform weight per unit length. what is the best position for the slings if the bending moment due to the weight of the girder is to be kept to a minimum?

At flow nozzle is to be installedin a 5-in type k copper tube carrying linseed oil at 77 f. a mercury manometer is to be used to measure the pressure difference across the nozzle when the expected range of the flow rate is from 700 galmin to 1000 gal/min. the manometer scale ranges from 0 to 8.0 in of mercury determine an appropriate diameter of the nozzle.
