Marks: +1, -0

Consider two RCC beams, P and Q, each of width 400 mm and effective depth 750 mm, made with concrete having a τ_{c max} = 2.0 MPa. For the reinforcement provided and the grade of concrete used, it may be assumed than τ_{c max} = 0.75 MPa. If the design shear for the beams P and Q is 400 kN and 750 kN, respectively, which of the following statements is true considering the provisions of IS 456-2000?

Shear reinforcement should be designed for 175 kN for beam P and the section for beam Q should be revised
Nominal shear reinforcement is required for beam P and the shear reinforcement should be designed for 120 kN for beam Q
Shear reinforcement should be designed for 175 kN for beam P and the section for beam Q should be designed for 525 kN for beam Q
The sections for both beams, P and Q need to be revised
