Comments:          
Specimen Identification: FP means the beam is a folded plate.      
Beam 1, Beam 2, Beam 3: shows the failure load. The failure load is when the beam collapsed.  

The failure load is not always the same because the different beams had different weaknesses.

Average: shows the average of the failure loads. The average is found by adding the three failure load results together and dividing it by three.
