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

: Write a function "def countWords(string)" that returns a count of all words in an input string represented by the variable 'st

Zina [86]

We can define a word as a group of characters without a space between them. To find the words of the input string , w can use split(delimiter) which returns a list of strings which had the defined delimiter between them in the input string.

def countWords(string):
words = string.split(" ")
count = len(words)
return count

Here we set the delimiter as the space character, and returned the length of the words list. I split each step into its own line for readability, however the function could be one line:

return len(string.split())

Here, no delimiter is specified. If one isn't given, it will default to split at any whitespace, including space.

Dns uses udp instead of tcp. if a dns packet is lost, there is no automatic recovery. does this cause a problem, and if so, how

grandymaker [24]

Packet loss is typically resolved by time-outs and retries. For applications where a duplicate operation doesn't matter this is acceptable.
