Use LRFD and select a W10 shape for an axially loaded column to meet the following specifications: - The length is 25 feet. - Both ends are pinned and there is bracing in the week direction at a point 10 feet from the top. - The service dead load is 150 kips, and the service live load is 320 kips.

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false

The process in which the system pressure remain constant is called a)-isobaric b)-isochoric c)-isolated d)-isothermal

Air at a pressure of 1atm and a temperature of 40 c is in parallel flow over the top surface of a flat plate that is heated to a uniform temperature of 120 c. the plate has a length of 0.40m (in the flow direction) and a width of 0.15m. the reynolds number based on the plate length is 50, 000. what is the rate of heat transfer from the plate to the air? if the free stream velocity of the air is doubled and the pressure is increased to 10 atm what is the rate of heat transfer?
