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 harmonically with an angular frequency of 200 rev min–1, its maximum speed is

• A. 25 m min–1
• B. 50 m min–1
• C. 100 m min–1
• D. 200 m min–1

Answer 1

Answer: (C)

100 m min–1

Answer 2

Here, $A = \frac{1}{2}m,\omega = 200rev\min^{- 1}{}$

$\therefore{\nu\frac{1}{2}\min^{- 1}}_{\max}$
