A Barnes and Books is interested in purchasing a two-story building for a new
retail store. They plan to use the first floor as the display/sales area and the
second floor for storage of inventory. Before buying the property, they have sked
you to verify the building will be safe for the intended use. You must determine if
the interior columns will carry a load of 32 kips (32,000 lbs.), the columns rest on
spread footings which are 4'-0" X 6'-0" X 1'-6" thick. Note the column load does
not include the weight of the footing. If the footing rests on silty sand can the
Does footing safely carry the column load?

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.

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.
