Ahollow circular column of external diameter 200 mm and thickness 5 mm is 6 m long. for the material properties of the column, a column is considered short if the slenderness ratio is less than or equal to 70 a yield stress of 280 mpa to a proportional limit of 210 mpa may be used. find the load capacity of the column.

Two technicians are discussing the intake air temperature (iat) sensor. technician a says that the computer uses the iat sensor as a backup to the engine coolant temperature (ect) sensor. technician b says that the powertrain control module (pcm) will subtract the calculated amount of fuel if the air measures hot. who is correct
