Una máquina industrial que pesa 4,905 N es soportada por 8 resortes helicoidales con una constante de rigidez individual de 16,000 N/m. Si una fuerza armónica F(t)=150∙sen(125t) N actúa en el sistema, determine: (a) la amplitud de vibración y (b) el ángulo de fase de la vibración.

If the thermal strain developed in polyimide film during deposition is given as 0.0044. assume room temperature is kept at 17.3 c, and thermal coefficient of expansion for the film and the substrate are 54 x 10^-6c^-1 and 3.3 x 10^-6c^-1respectively. calculate the deposition temperature.

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

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false
