Homework Statement
You have a new job designing rides for an amusement park. In one ride, the rider's chair is attached by a 9.0-m-long chain to the top of a tall rotating tower. The tower spins the chair and rider around at the rate of 1 rev every 4.0 s. In your design, you've assumed that the maximum possible combined weight of the chair and rider is 150 kg. You've found a great price for chain at the local discount store, but your supervisor wonders if the chain is strong enough. You contact the manufacturer and learn that the chain is rated to withstand a tension of 3000 N.
Will this chain be strong enough for the ride? Yes or no?
Homework Equations
F=(m)(w^2)(r)
The Attempt at a Solution
I converted 1rev/4seconds to rad/s-
.25rev/s x 2(pi) = 1.571rad/s
Then plugged it in and was confused!
F=150kg x 1.571 x r
what should I use for r?
or if i put 3000N in for F instead r comes to be 12.73m
I don't know what to do with these numbers someone please help!
Thank you
