In the context of construction materials, which of the following statements is/are CORRECT?
The design shear strength of a reinforced concrete rectangular beam with a width of 250 mm and an effective depth of 500 mm , is 0.3 MPa . The torsional moment capacity of the section (in kN.m) under pure torsion, as per IS 456:2000, is _________ (round off to one decimal place).
Consider a reinforced concrete beam section of 350 mm width and 600 mm depth. The beam is reinforced with the tension steel of $800 \mathrm{~mm}^2$ area at an effective cover of 40 mm . Consider M20 concrete and Fe415 steel. Let the stress block considered for concrete in IS 456:2000 be replaced by an equivalent rectangular stress block, with no change in (a) the area of the stress block, (b) the design strength of concrete (at the strain of 0.0035), and (c) the location of neutral axis at flexural collapse. The ultimate moment of resistance of the beam (in kN.m) is __________ (round off to the nearest integer).
