A piston in a car engine has a mass of 0.75 kg and moves with motion wich was approximately simple harmonic. If the amplitude of zis oscillation is 10 cm and z max. safe operating speed of z engine is 6000 rev. per min. Calculate:
a. Max acceleration of z piston
b. Max.speed of the piston
c. The max. Force acting on the piston

  • physics -

    6000 rpm = 628.3 radians/sec
    Call that angular frequency "w"

    Maximum acceleration = (Amplitide)*w^2
    = 0.10 m * w^2 = 39480 m/s^2

    Maximum velocity = (Amplitude)*w = 62.83 m/s.

    Max force = (Mass)*(max acceleration)
