QUESTION $2$

Consider the curved dam shown below. The curved face of the dam is described by the equation,

$y=\frac{x^2}{A}$

where $x$ and $y$ are in $mm$ and the constant $A$ is obtained from the table of parameters below.

Table of dimensions

Dam height $(H)$:$,15649mm$

Constant $(A)$:$,2568mm$

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 $(F_{\text{v}\text{e}\text{r}\text{t}})=$

$8\frac{N}{m}$

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 $()=$

$8$
