**1. The problem statement, all variables and given/known data**

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__.

Is the chain strong enough?

**2. Relevant equations**

w=v/r

Fr=Tcos(theta)

Fz=n-Fg=0

**3. The attempt at a solution**

Find tension that is supported by the system, and compare it to the 3000N.
