## Homework Statement

A mass m is suspended from a spinning rod by two massless cords of equal length L, held fixed at points along the rod D meters apart. It is observed that m moves in a circle with a tangential velocity v, find the ratio of the tensions between the two supporting cords

## Homework Equations

Newton's three laws of motion

## The Attempt at a Solution

I didn't get terribly far on this one; I focused too much time on frictional forces during study.

I set up the problem, showing an isoceles triangle pointing rightward (with the mass m at the nexus), and angles θ

_{1}and θ

_{2}. I didn't get too much farther due to time constraints while actually taking the test, and the instructor himself won't be available to answer it for close to a week. Any help is appreciated.

I can post an image of what I did once I get home, in case it helps.
