Chapter 1 and 2 "The Revolt of Engineers": Layton describes the approaches of the four founder societies of engineering professionals--ASCE, AIME, ASME, and AIEE. In 3-4 sentences, state which of these organizations would be most appealing to you to join based on its membership criteria, stances on professional behavior, and relationship to business, and why. In 1-2 sentences, state which would be least appealing and why?

A square footing 4 m × 4 m is located at a depth of 1.0 m in a layer of saturated clay 13 m thick, a firm stratum lies immediately below the clay. Characteristic parameters obtained from oedometer and triaxial tests for the clay are as follows: A= 0.42, cu =100 kPa, , u  0 c' 0, ' 32, 0.065 / , 2 mv  m MN 3  sat  21kN / m , Eu = 300cu. Determine the total settlement under the centre of the footing carrying a net pressure of 200 kPa using Skempton-Bjerrum method.

A) draw the stres-strain diagram for a typical steel bar under tensile test showing all details of the results of the test.

B) A material like aluminium does not have an abviouse yield point and undergoes large starin after the proportionality limit draw the sketch to show how the arbitrary yield stress is determined.
C) ASteel sample of diameter 30mm and guage length 60mm gave under tensile test the following results.
a) load at limit proportionality 70,000N and the extension 0.045mm.
b) load at yield 80,000N.
c) maximum load 130,000N
the two parts where joined together after being broken.the length between guage points was found to be 80mm and the diameter at the neck 20mm calculate:-

1) the modulus of elasticity E?
2) the stress at the limit proportionality?
3) yield stress?
4) ultimate limit stress?
5) percentage elongation?
6) percentage cinstruction?

Write a detailed note on Richter and Mercalli intensity scale of earthquake. Also draw comparison between both. Plagirism is must be less than 15%.

Based on jar test results, 51 mg/L of alum is used to coagulate a sample containing 114 mg/L suspended soids. How many mg/L as CaCO3 of natural alkalinity are consumed? What is the mass rate of sludge generated if suspended solids are reduced to 10 mg/L? Assume Al(OH)3 is precipitated (EW=26.0 mg/meq). The plant treats 100,000 gpd.
