Results obtained from a tension test on a bar of uniform cross section 10 mm x 10 mm subjected to an axial pull of 8000 N were tabulated. The lateral dimensions of the bar were found to be changed to 9.9985 mm x 9.9985 mm while using a material having modulus of rigidity equal to 0.8 x 107 N/cm2. By determining the values for different moduli, identify the properties of material and establish the relationship between them. What changes will happen to the volume if the length of the bar is equal to 2.5 m? Based on the results obtained discuss how the elastic constants are related to the deformation of the bar?

Q2: For analyzing a structure, shear force and bending moment diagrams were plotted for a simply supported beam of span 8 m when subjected to a uniformly distributed load of ‘w’ kN/m over a length of 4 m from the left end support, a point load ‘2.4 w’ kN at a distance 6 m from the left end support and another uniformly distributed ‘0.6 w’ kN/m at a distance 2 m from the right end support. It was noted that the magnitude of shear force at distance 4 m from the left end support is equal to (-12.5 kN). Suggest a suitable value for ‘w’ based on the given data. How it will change the reactions at the supports, shear force and bending moment values. By plotting bending moment and shear force diagram for the beam briefly conclude the relationship between the values for shear force and bending moment.

a) Explain the major causes of kick as related to the well control.
b) There are two major methods usually used in killing the well "the driller method" and "wait and weight method." Suppose that you have the following situation. Which method you will choose. Explain and justify your answer. ​​​​
• Shortage of crew members for mixing.
• Shortage of heavy material (Barite) to prepare a kill mud.
• Un-skillful people to do a complicated calculation.
• Time is not crucial.
  
c) What do you understand from the following terms used in the well control:​
i. Secondary well control
ii. Dynamic Bottom hole pressure
iii. Circulating pressure
iv. Kick warning signs
d) While drilling a well, a kick was detected at 10100 ft depth, the driller immediately closed in the well and recorded following data was data:
Hole diameter = 8 1/2 inch
Mud weight = 13.2 ppg
Shut in drill pipe pressure (SIDPP) = 530 psi
Shut in casing pressure (SICP) = 800 psi
Pit gain =14 bbls
Assuming that the slow pump rate @30 SPM = 360 psi and the
Annular pressure loss (APL) = 210 psi
Calculate each of the following:
i. Dynamic hole pressure (DHP)
ii. Killing mud weight (KMW)
iii. Equivalent circulating density (ECD)
iv. Maximum allowable annular surface pressure(MAASP)

Compute |A|, the determinant of A (note: rounding errors during computation may cause Matlab to return a value like 6.2137e-16 in place of 0; in such cases, write 0 as your answer; though not necessary, you can verify the answer by computing the value of the determinant by hand). State the Matlab function you use to compute the determinants.

Using 7/8 in diameter ASTM A325-N bolts in standard holes and E70 electrodes. Design a bolted flange-plated FR moment connection between a W12×50 beam and a W14×90 column flange (RD = 15 kips; MD = 60 kip-ft) and (RL = 30 kips; ML = 120 kip-ft). For shear plate use three bolts:

(I) Check the beam available flexural strength

(ii) Design single-plate web connection

(iii) Check the connecting elements rupture strength at welds

Sketch the connection.

A tangent section of highway has a -1.0% grade and ends at station 0+145 and
elevation 26 m. It must be connected to another section of highway that has a -1.0% grade and that
begins at station 1 + 350 and elevation 40 m. The connecting alignment should consist of a sag
curve, constant grade section, and crest curve, and be designed for a speed of 80 km/h. What is the
lowest grade possible for the constant grade section that will complete the alignment?
