MOHR-COULOMB FAILURE CRITERIA:
In 1900, MOHR-COULOMB states Theory of Rupture in Materials which defines as “A material fails due to because of a critical combination of normal and shear stress, not from maximum normal or shear stress”. Failure Envelope is approached by a linear relationship.
If you can not understand the below symbols see the attachment below
f f ()
Where: f = Shear Stress on Failure Plane
´= Normal Stress on Failure Plane
See the graph in the attachment
For calculating the shear stress, when Normal stress, cohesion and angle of internal friction are given. Use this formula: shear stress = f c tan
Where,
• f is Shear Stress on Failure Plane
• c is Cohesion
• is Normal Total Stress on Failure Plane
• is Friction Angle
Disk defragmentation realigns separated data so that related file pieces are unified. <span> Defragmentation is is the process of consolidating fragmented files on the user's hard drive.</span>This Microsoft Windows utility includes <span>rearranging the fragments and restoring them into fewer fragments or into the whole file.

Question: The question is incomplete. See the complete question below;
Consider the following situation using NAT (Network Address Translation), where the router uses one public IP address, 138.76.29.7, for several hosts with private IP addresses. The NAT table already has the information as shown due to previous communications.
Answer:
Source IP = 208.38.69.1
Source port = 3006
Explanation:
Network Address Translation (NAT) simply means the translation of one or more local IP address so as to provide internet access to local hosts. In this case, the router uses one public IP address and with private IP address.
