New page

In part a) the resultant <math>\mathbf{R}</math> is seen to be

<math>\begin{align}
& \mathbf{R} =11\textrm{.}1\mathbf{i}+3\textrm{.}93\mathbf{j} \ \text{N}\\
\end{align}</math>

Also according to the theory

<math>\tan \alpha =\frac{V}{H}</math>
where <math>H</math> is the horizontal component of the resultant and

<math>V</math> is the verical component of the resultant.

Thus

<math>\tan \alpha =\frac{\text{3}\textrm{.}\text{93}}{\text{11}\textrm{.}\text{1}}=0\textrm{.}354</math>

giving

<math>\alpha =19\textrm{.}5{}^\circ</math>
