A 1/2-13 UNC-2A grade 5 bolt is to be used as a fastener in a connection. The bolt will be loaded to 80 % of its proof strength. The bolted joint has a joint constant of C = 0.21. A load of P = 8400 lbs is applied to the bolted joint. Determine the factor of safety in the bolt using the Proof Strength as the failure strength. Express your answer to exactly one decimal place.
Answer must be
