A threaded rod with 12.0 turns / cm and 1.18 cm in diameter is mounted horizontally. I screwed a threaded rod with a hole to attach to the bar. The bar rotates at 237 revolutions / min. How long will the bar to travel 1.50 cm threaded rod? I tried using the data of the diameter but could not. Help me!

Hi Mario, and welcome to Physics Stack Exchange! This is not primarily a homework help site, it's a site for conceptual questions about physics, so we expect you to narrow down your question to the specific concept that is giving you trouble and ask about that. If you do that, I'll be happy to reopen the question. You can find more information about homework-like questions on meta. – David Zaslavsky♦ Nov 1 '11 at 6:41
