First Year Engineering (Semester 2)
TOTAL MARKS: 100
TOTAL TIME: 3 HOURS
(1) Question 1 is compulsory.
(2) Attempt any four from the remaining questions.
(3) Assume data wherever required.
(4) Figures to the right indicate full marks.
1(a) Explain scope of civil Engineering(7 marks)
1(b) Describe briefly the seven elements involved in Remote sensing process.(7 marks)
2(a) Explain point to be consider in planning of industrial building.(7 marks)
2(b) Write the abbreviations for DPC, GI, RCC, FSI, W.C, LM, GL, RWP. Draw symbols for Meter, Bell, anhole, Wood, Bracket fan, Revolving door,(7 marks)
3(a) Discuss various methods and formulae to compute area and volume.(7 marks)
3(b) The area of the plan of an old map plotted to a scale of 10 meters to 1 cm measures now as 100.2 sq cm as measured by a planimeter. The plan is found to have shrunk so that a line originally 10 cm long now measures 9.7 cm only. Further the 20 m chain used is 8 cm too short. Find the true area of the survey.(7 marks)
4(a) Discuss various construction material and explain the different types of paints used in building construction(7 marks)
4(b) Discuss use and properties of Wrought iron.(7 marks)
5(a) Define True meridian, Back bearing, Isogonic and Agonic line, Declination and Dip.(4 marks)
5(b) Find the included angles between line AB and AC if the bearings are
AB 60°10' AC 245°10'
AB N10°50'E AC S40° 40'E (Reduce bearing)
AB N30°25'E AC N30°W(Reduce bearing)(3 marks)
5(c)
The following is the page of a level field book. Fill in the missing readings and calculate the reduced levels of all the points. Apply the usual checks.
