Chapter 06, problem 6.43 for some metal alloy, a true stress of 345 mpa (50040 psi) produces a plastic true strain of 0.02. how much will a specimen of this material elongate when a true stress of 414 mpa (60050 psi) is applied if the original length is 450 mm (17.72 assume a value of 0.22 for the strain-hardening exponent, n.

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.

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

Which of the following components of a pid controlled accumulates the error over time and responds to system error after the error has been accumulated? a)- proportional b)- derivative c)- integral d)- on/off.
