3. Answer any FOUR Questions from Part-B
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
PART ?A
1. a) Give the relation between E, N, and K. Mention its importance. (2M)
b) Explain the theory of simple bending. (3M)
c) Give a brief note on Lame?s equation. (3M)
d) List out the uses of compressed air. (2M)

PART -B
2. a) Explain the typical stress-strain curve with a neat sketch, obtained from a direct
tension test on a mild steel rod and explain the salient points. (7M)
b) A 500 mm diameter circular reinforced concrete column is having 8 bars of 20
mm diameter. The column is subjected to an axial thrust of 875 kN. Determine the
stresses developed in concrete and steel. Assume Esteel = 12Econcrete. (7M)
3. Define Neutral axis. Sketch the bending stress distribution across the cross section
of a rectangular beam section 230 ? 400 m subjected to 60 KNm moment. (14M)
