The diagram shows a child with a mass of 45 kg hanging 2 metres from the left end of a structure, and an adult with a mass of 85 kg hanging 1 metre from the right end. \begin{array} {ll}
\text{R}_\text{L} = \text{............................... N} & \text{Direction ...............................} \\
& \\
\text{R}_\text{R} = \text{............................... N} & \text{Direction ...............................} \end{array}
i. \( \text{R}_{\text{L}}=860\ \text{N} \uparrow \) \( \text{R}_{\text{L}}= 440\ \text{N} \uparrow \)
ii. 
i. \( \stackrel {\curvearrowright} {\sum{ \text{M}}{^{+}_\text{L}}}: \) \( \sum \text{F}_\text{V} \uparrow:\)
\(0\)
\(=(2 \times 450)+(4 \times 850)-(\text{R}_\text{R} \times 5) \)
\(5 \times \text{R}_\text{R}\)
\(=900 + 3400\)
\(\text{R}_\text{R}\)
\(=860\ \text{N} \uparrow \)
\(0\)
\(= -450-850+860+\text{R}_\text{L} \)
\( \text{R}_{\text{L}}\)
\(= 440\ \text{N} \uparrow \)
ii.
