Answer to Question #161288 in Mechanical Engineering for Johan Nieuwoudt

Question

TENSILE TEST ON MILD STEEL

Calculate the Factor of Safety if you've got the following:

Yield Stress - 550 Mpa

Ultimate Stress - 950 Mpa

Design Stress - 325 Mpa

Answer 1

Factor of Safety =$\frac{maximum strength}{design load}$

maximum strength =

design load = 325 mpa

factor of safety = $\frac{950 }{325}$

= 2.923
