The pistons in an internal combustion engine undergo a motion that is approximately simple harmonic?

The pistons in an internal combustion engine undergo a motion that is approximately simple harmonic

If the amplitude of motion is 3.4cm , and the engine runs at 1500rpm ,

find the maximum acceleration of the pistons.

Find their maximum speed.The pistons in an internal combustion engine undergo a motion that is approximately simple harmonic?T=2*蟺*sqrt(m/k)

T=1/(1500/60)



sqrt(k/m)=2*蟺/0.04



amax=A*(k/m)

amax=0.034*(2*蟺/0.04)^2

838 m/s^2



vmax=A*sqrt(k/m)

vmax=0.034*2*蟺/0.04

5.338 m/s
