Centripetal Ride: Chain Rated@3000N - Will it Hold?

[kevi555]

A chair is attached by a 9.0m long chain to the top of a tall rotating tower. The tower spins the chair and rider around at a rate of 1 Rev. every 4.0s. Max weight of the chair & rider is 150kg. You buy chain rated@3000N of tension. Will that chain be strong enough?

Can you show some of your working? If you read the forum rules we will not do your homework for you.

I have the same problem as posted above. what i have come with so far is that Fnet = Ft-Fg. Where Ft is the tension in the chain. which i figure to be m*[v^2/r]. And Fg is gravity m*g. Then i simply subtracted them to get the Fnet. Then compared them to 3000N chain. Am I on the right track with the problem?
