WebThe factors of safety vary in magnitude depending on which condition is being considered. For example, the factor of safety used to determine the design limit load from the flight limit load is of the order 1.4–1.5 and the factor of safety used to obtain the ultimate load from the design limit load is in the range 1.25–1.5. WebNow, the factor of safety is given by, (F.O.S.)= = Syt σy = S y t σ y = 300 84.85 = 300 84.85 = 3.53 F.O.S. = 3.53 Therefore the FOS by using the maximum shear stress theory is 3.53.
