For analyzing a bridge, bending moment diagrams were plotted for a simply supported beam of span 5 m when subjected to a uniformly distributed load of magnitude ‘w’ kN/m over the entire span. It was noted that maximum bending moment is equal to 37.5 kNm. Suggest a value for ‘w’ based on the requirements. How it will change the reactions at the supports? What happens to the shear force and bending moment values at the supports and at the center? By plotting bending moment and shear force diagrams for the beam briefly conclude the relationship between the
values for shear force and bending moment.

What consequences does a client face when a mishap occurs in a project? Please give a detailed answer.

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?   

Can a soil swell during shearing? List two field examples where this can be observed?

The urban tram project, which operates with a light rail system, is planned. In addition to metaformic, sedimentary and magmatic rocks on the ground, unconsolidated fine sand-silt grain size ground materials were also found. Underground water level depth is between 1 and 3 meters. There is a fault zone along the project line. What can be the geotechnical problems that may be encountered before, during and after the project construction, and solutions as a civil engineer?

A clay layer in field is 3-m thick and is sandwiched between two sand layers (drained from top and bottom). The saturated stratum of clay is under a surcharge loading and underwent 90% primary consolidation in 75 days. The time required in minutes for a 30 mm thick undisturbed clay sample obtained from the field to undergo 90% consolidation in laboratory is most nearly equal to

1. In 2015, countries around the world agreed to develop a new set of global goals to eradicate extreme poverty and achieve sustainable development by 2030 through 17 Sustainable Development Goals (SDGs) for the future of the world. No goal or target is considered met unless met for all people, whoever and wherever they are.

a) Briefly explain what the concept of sustainable development means.

b) Illustrate the three pillar model of sustainability. Comment on some of the challenges for sustainable development in our country and suggest a way to overcome the same.

c) The SDG #7 is to ensure access to affordable, reliable, sustainable and modern energy for all.

(i) Differentiate between conventional and non-conventional energy sources. Which will you support? Why?

(ii) Going green can reduce the overall energy use. Mention any two strategies that you could adopt to meet the sustainability benchmarks.

2. Air pollution in Asia has worsened since 2000 and is responsible for deaths of thousands of people in Beijing, Jakarta, Seoul and Manila. The pollution is a result of the use of fossil fuels by the industry and transport sectors. The problem got aggravated in Asia due to the use of poor quality fuel, inefficient method of energy production, use of vehicles in poor condition and traffic congestion. This was revealed during a research conducted by World Bank and Stockholm Development Institute. The research states that air pollution in the continent has surpassed the combined emissions in Europe and North America. The deaths caused by fine particulate matter far exceed those caused by sulphur dioxide, nitrogen oxide, ozone and lead. The health cost in major Asian cities now exceed for 15-18 percent of urban income expenditure, claims World Bank officials.

a) A comprehensive campaign to address air pollution need to be launched through school children, what programme (one) would you envisage for this. What is outcome anticipated?

b) There is a sudden decision to remove all vehicles from the road that fails to meet specified norms of emission level within a specified time period. As part of citizen forum you are requested to give views on the enforced regulation. State your views on this.

c) A massive campaign on environmental degradation is to be initiated. Bring out a slogan and the key message that need to be addressed.

d) Suppose you are a Carbon Credit Auditor appointed to assess the greenhouse gas emission reduction strategies. Identify a component of assessment and brief the methodology that could be adopted in connection with this.
