Answer:
theoretical fracture strength = 16919.98 MPa
Explanation:
given data
Length (L) = 0.28 mm = 0.28 × 10⁻³ m
radius of curvature (r) = 0.002 mm = 0.002 × 10⁻³ m
Stress (s₀) = 1430 MPa = 1430 × 10⁶ Pa
solution
we get here theoretical fracture strength s that is express as
theoretical fracture strength =
.............................1
put here value and we get
theoretical fracture strength =
theoretical fracture strength =
theoretical fracture strength = 16919.98 MPa
Hope that helps had to do it myself http://160592857366.free.fr/joe/ebooks/Mechanical%20Engineering%20Books%20Collection/FLUID%20MECHANICS/Fundamentals%20of%20Fluid%20Mechanics%204th%20Edition%20-%20Munson%20-%20John%20Wiley%20and%20Sons/MUNSON%20-%20livro.pdf
