Problem $1$: A $350$ mm thick wall footing is to support a $300$ mm thick concrete wall supporting a uniform dead load of $150k\frac{N}{m}$ and uniform live load of $175k\frac{N}{m}.$ The base of the footing is $1\mathrm{.}8$ m below the natural grade where the soil weighs $15\mathrm{.}6k\frac{N}{m^3}.$ Concrete weighs $23\mathrm{.}5k\frac{N}{m^3},f{c}^{\text{'}}=27\mathrm{.}5$MPa,$fy=300$MPa. Allowable soil bearing pressure $=180$kPa and clear concrete cover is $75$ mm $.$ Use $16$ mm diameter for main reinforcement and $12$ mm diameter for temperature reinforcement. Determine the following $(1$ point each$)$:

a$.$ Effective depth in mm

b$.$ Net soil pressure in kPa

c$.$ Width of the footing in $m($round up to nearest $1$ decimal place$)$

d$.$ Ultimate soil pressure in kPa

e$.$ Shear force at critical section in kN

f$.$ Nominal shear stress in MPa

g$.$ Ultimate moment at critical section in $kN-m$

h$.$ Rn in Mpa

i$.$

j$.min$

k$.$ As for main reinforcement in $m{m}^2$

Spacing of main bar in mm $($round down to nearest whole number$)$

m$.$ Number of temperature bar
