Answer:
The following command is issued
in Windows command prompt
followed by the HTTP GET
message to the “utopia.poly.edu"
web server:
> telnet utopia.poly.edu 80
As the index.html page in the web
server was not modified since
Mon, 18 May 2015 09:23:34GMT,
the following outputwas displayed
when the above commands were
issued on Sat, 23 May 2015.
The first 4 lines are the GET
message and header lines input by
the user.
The next 4 lines (starting from
HTTP/1.1 304 Not Modified) are
the response from the web server.

Answer:
1788.9 MPa
Explanation:
The magnitude of the maximum stress (σ) can be calculated usign the following equation:
<u>Where:</u>
<em>ρ: is the radius of curvature = 2.5x10⁻⁴ mm (0.9843x10⁻⁵ in)</em>
<em>σ₀: is the tensile stress = 100x10⁶ Pa (14500 psi) </em>
<em>2a: is the crack length = 4x10⁻² mm (1.575x10⁻³ in) </em>
Hence, the maximum stress (σ) is:
Therefore, the magnitude of the maximum stress is 1788.9 MPa.
I hope it helps you!
