A Charpy V Notch test was conducted for an ASTM A572 Grade 50 bridge steel. The average values of the test results at four different test temperatures were found to be

10 ft. lb at 50 degrees F, 15 ft. lb at 0 degrees F, 40 ft. lb at 40 degrees F, 60 ft. lb at 100 degrees F.

The bridge will be located in a region where specifications require a minimum of 25 ft. lb fracture toughness at 30 degrees F for welded fracture-critical members. If the bridge contains a welded flange in a fracture-critical member, does the steel have adequate Charpy V notch fracture toughness? Show your supporting calculations.
