Question

If the eyebolt is made of a material having a yield stress of ?Y = 245MPa , determine the minimum required diameter d of its shank. Apply a factor of safety F.S. = 1.5 against yielding. Express your answer to the nearest mm and include the appropriate units.

Answer 1

Step-by-step explanation:

Factor of Safety= Material Strength / Design Load

∵ designload =⁰y /F.S

=254/1.5

=163.33Mpa

stress=force / area

=163.33×10⁶N/m²=30000N / π/4d²

d²=233.86×10⁻⁶

d=15.2×10⁻³m
