At 70 degrees F a rigid slab weighing 120,000 lbs is placed upon two bronze rods

Question

At 70 degrees F a rigid slab weighing 120,000 lbs is placed upon two bronze rods and one steel rod. At what temperature will the stress in the steel rod be zero? For steel: A = 10 sq in., E = 30 x 106 psi, and ? = 6.5 x 10-6. For each bronze rod: A = 10 sq in., E= 12 x 106 psi, and ? = 10.5 x 10-6. The steel rod and the two bronze rods are not the same length. the steel rod is 12 ft long and the two bronze rods are 10ft long. The rigid slab sits level on top of all of the rods, the steel rod is in the middle and sits in a little gulley or a space where it needs that extra two feet to reach the ground. this question comes with a picture but i couldnt upload it. The only measurements it gives for length or spacing or anything is the length of the 3 rods which i have specified. Hope this helps, the diagram for the problem is very simple if this sounds confusing.
