Acylindrical bar that has its lateral surface constrained so that there can be no lateral expansion is then loaded with an axial compressive stress σ . (a) find σ22 and ơ33 in terms of σ and the poissons ratio v, and (b) show that the effective young's modulus eeff = σ11/€11 is given by eeff = (1-v)/(1-20-202)

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?

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
