Correct Answer: decreased gradually towards the edge
3. An R.C.C. column of 30 cm diameter is reinforced with 6 bars 12 mm ? placed symmetrically along the circumference. If it carries a load of 40, 000 kg axially, the stress is
5. For stairs spanning l metres longitudinally between supports at the bottom and top of a flight carrying a load w per unit horizontal area, the maximum bending moment per metre width, is
9. If bending moment is M, shear force is F effecive depth is d, lever arm is la area of reinforcement is As and sum of the circumferences of main reinforcement is 0, the bond stress based on working stress method, is
10. A reinforced concrete cantilever beam is 3.6 m long, 25 cm wide and has its lever arm 40 cm. It carries a load of 1200 kg at its free end and vertical stirrups can carry 1800 kg. Assuming concrete to carry one-third of the diagonal tension and ignoring the weight of the beam, the number of shear stirrups required, is
