QUESTION $2($A$)$

Determine the magnitude of the horizontal component of the hydrostatic force per unit length $($to the nearest Newton$)$ acting on the curved surface of the dam.

Report your answer in Newtons and use this rounded value in subsequent calculations.

The horizontal component $(F_{\text{h}\text{o}\text{r}})=$

$8\frac{N}{m}$

QUESTION $2($B$)$

Determine the magnitude of the vertical component of the hydrostatic force per unit length $($to the nearest Newton$)$ acting on the curved surface of the dam.

Report your answer in Newtons and use this rounded value in subsequent calculations.

The vertical component $(F_{\text{v}\text{e}\text{r}\text{t}})=$ O $8\frac{N}{m}$

QUESTION $2($C$)$

Determine the magnitude of the resultant hydrostatic force per unit length $($to the nearest Newton$)$ acting on the curved surface of the dam.

Report your answer in Newtons.

The resultant hydrostatic force $(F_{\text{r}\text{e}\text{s}})=8\frac{N}{m}$

QUESTION $2(D)$

Determine the angle in degrees $($to the nearest $0\mathrm{.}1$ degrees$)$ that the resultant hydrostatic force makes with the positive $x-$axis.

Report the angle measured clockwise from the positive $x-$axis.

The angle of the hydrostatic force $()=$

$8$
