Correct Answer: tangent is equal to the rate of the maximum resistance to sliding on any internal inclined plane to the normal pressure acting on the plane
3. If diameter of a reinforcement bar is d, the anchorge value of the hook is
5. An R.C.C beam of 25 cm width has a clear span of 5 metres and carries a U.D.L. of 2000 kg/m inclusive of its self weight. If the lever arm of the section is 45 cm., the beam is
6. If At is the gross area of steel in tension, d is the effective depth of the beam and y is the depth of the centre of gravity of the resultant compression, the moment of resistance M of the beam, is given by
Correct Answer: 0.1 L from the centre edge of column
8. In a doubly-reinforced beam if c and t are stresses in concrete and tension reinforcement, d is the effective depth and n is depth of critical neutral axis n, the following relationship holds good
