(Answered) A 66-kg sign hung centered from a uniform rod of mass 82 kg

Academics

A 66-kg sign hung centered from a uniform rod of mass 8.2 kg and length 2.3m. At one end the rod is attached to the wall by a pivot, ans the other end it's supported by a cable that can withstand a maximum tension of 800N.

what is the minimum height h above the pivot for anchoring the cable to the wall?
