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?

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.
