Question

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

Answer 1

a = \(\frac{1}{2}\)m, ω = 200 rev/min

U_max = aω = \(\frac{1}{2}\) × 200m/min = 100 m/min.
