A concrete column $$200 \times 200 mm$$ in cross-section is reinforced with steel bars of $$1200 mm^2$$, total cross-sectional area. Calculate the safe load for the column if permissible stress in concrete is $$5 N/mm^2$$ and $$E_s$$ is $$15 E_c$$

For design of Flexure members, the strain in the reinforcing bars under tension at ultimate state as per IS 456-2000 shall not be less than

If the moment of inertia of a section about its axis is I and its effective sectional area is A, its radius of gyration r about the axis is

A uniform cantilever beam has a span of 2m and carries a point load of 6kN at free end. The magnitude of moment to be applied at free end for zero vertical deflection at that point is (neglect self-wt. of the beam)

A bar 40mm in diameter and subjected to a tensile force of 40,000 kgs. Undergoes elongation resulting in decrease in diameter considering the properties of the material as $$E = 2 \times 10^5 N/mm^2$$ and Poisson’s ratio $$\upsilon$$ as 0.3, the modulus ofrigidity will be:
