The ultimate strength of a steel rod is 550.000MPa. If the factor of safety of 3.000 is required, what is the maximum permissible load for the rod if it has a diameter of 4.100cm?

ANS = kN (Round to 3 decimal places)

ultimate strength = 550.000MPa

Factor of safety = 3.000

Rod diameter = 4.100cm = .041m

Not sure how to find the maximum permissible load for the rod. Need some help please. Thank you.
