Question

The piston in the cylinder head of a locomotive has a stroke (twice the amplitude) of 1.0 m. If the piston moves with simple harmonic motion with an angular frequency of 200 rad/ min, what is its maximum speed?

Answer 1

Stroke = 1 m

Amplitude = (troke/2) = 1/2 m

ω = 200 rad / min

V_max = ωA

= 200 × 1/2

= 100 m / min

V_max = 1.67 m/s.
