## Homework Statement

A ball with the mass

**m**is attached to a rod, suspended by two strings both with lengths

**L**.

The rod is rotating with the angular velocity

**ω**and the ball rotates with it in such a way that the strings are taut and the ball moves in a circular pattern. I tried to draw it on my computer farily accurate.

**(See attached image)**The first task is to provide a relationship between the tensions in the strings. (The upper tension over the lower tension.)

And the second is to determine the minimum angular velocity ##ω## for the lower string to be taut.

## Homework Equations

I know that the centripetal acceleration ##a=ω^2r## and the centripetal force ##F_c=ma=mv^2/r##

## The Attempt at a Solution

So I have to get the X- and Y components of the tension force for each string. The weight ##w=mg## of the ball.

But I'm having real troubles to getting started. Any good tips on stuff that I've left out and how to tackle this one?

Thanks
