Using the concrete property from Q$4($a$)$ and assuming fyk $=500\frac{N}{m}m2,$

Concrete property:

Characteristic Strength: $35\frac{N}{m}{m}^2$ at $28$ days.

Standard Deviation: $12\frac{N}{m}{m}^2.$

Defective Rate: $1\%.$

Type of Cement: Ordinary Portland $($Class $42\mathrm{.}5)$ or Sulphate

Resistance Portland cement.

Maximum Water$-$Cement Ratio: $0\mathrm{.}6.$

Workability: Slump range of $10-30mm.$

Aggregate Size: Coarse aggregate cannot exceed $20mm$ in size.

Fine Aggregate: $70\%$ of fine aggregate must be finer than $600m$ in

size.

Cement Content: Ensure at least $300kg$ of cement per $1m^3$ of

concrete.

Determine the maximum shear force and maximum bending moment

$($hogging$)$ in the beam shown in Figure Q$5.$

If $3$ No$.20mm$ diameter reinforcing bars are provided for the tension and $3$

No$.20mm$ diameter reinforcing bars are provided for the compression

reinforcements, provide shear reinforcements for the span between the

supports in the beam in Figure Q$5$ and check the provided flexural

reinforcements against the limits in the code.
