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
50 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 degree 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.
Only attempt when you are sure ,else skip for others , otherwise I will downvote for wrong answers
