What is the factor of safety of a steel hanger having an ultimate strength of 550.000MPa and supporting a load of 79000.000N. The steel hanger in question has a cross sectional area of 7.000cm^2.

ANS = (Round to 3 decimal places)

ultimate strength = 550.000MPa

load = 79000.000N

area = 7.000cm^2 = .07m

Not too sure how to start. A little help would be greatly appreciated. Thanks.
