STABILITY OF SLOPES -

● FORCES CAUSING FAILURE OF SLOPES -
    1. Gravitational force
    2. Seepage force
    3. Earthquake force
    4. Construction equipment loads

● TYPES OF SLOPE FAILURES -
    1. Translational failure
    2. Rotational failure
    3. Wedge failure
    4. Compound failure

● TYPES OF SLOPES -
◇ Infinite slopes  -  natural slope
                            -  translational failure
                            - e.g mountain

◇ Finite slopes-  artificial slope
                       -  rotational failure
                       - e.g embankment of    
                                 road

STEEL

PLASTIC ANALYSIS -

● Shape factor -
• Ratio of plastic moment to elastic moment
• Ratio of plastic section of modulus to elastic section of modulus
• Shape factor for various sections

       Shape            Shape factor
    Rectangle               1.5
    T section                 1.883
    Circular solid          1.7
    Circular hollow        1.27
    Diamond                  2
    Triangle                   2.34

● Length of plastic section -

• It is length of beam over which moment is greater than end moments.

•  For point load   =>  Lp = L (1-1/s )
   For UDL            =>  Lp = L (1- 1/s)^½

• Number of plastic hinges is given as static indeterminacy plus one.

• Possible location of plastic hinges are
    i) At fixed ends
   ii) At geometric junction
  iii) Below point load
   iv) At point of zero shear for UDL

● Load factor -
LF = (s)(FOS )
where,     s = shape factor
            Fos = factor of safety

🔥 FLUID MECHANICS

Fluid Dynamics -
● Pitot tube -
•Used to measure velocity of flow
•Coefficient of variation = Cv
•Cv = actual velocity/ theoretical velocity
•Cv = 0.97

● Venturimeter -
•Used to measure discharge
•Coefficient of discharge = Cd
•Cd = actual discharge/ theoretical discharge
•Cd = 0.98

● Orifice meter -
•Used to measure discharge
•Coefficient of contraction = Cc
•Cc = area at venacontracta/ area at orifices
•Cc = 0.6

● Borda mouth piece -
• Cc = 0.7
