(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A heavy horizontal girder of length L has several objects suspended from it. It is supported by a frictionless pivot at its left end and a cable of negligible weight that is attached to an I-beam at a point a distance h directly above the girder's center. Where should the other end of the cable be attached to the girder so that the cable's tension is a minimum?

2. Relevant equations

F = Ma

Torque = I(alpha)

3. The attempt at a solution

In the y-axis I have:

mg = T sin(theta)

N = T cos(theta)

where do I go from here?
