The problem is as follows:

$\begin{array}{ll}

1.&15N\\

2.&25N\\

3.&35N\\

4.&45N\\

5.&55N\\

\end{array}$

This particular problem has left me confused at where should I put the vectors to find the reactive force. I'm assuming that the pulleys in the top are held to a fixed support i.e a wall, therefore its weight will not make part of the analysis.

But to me the problem is what to do with the reaction?. How can I find it?. I presume it is pointing upwards, but what it confuses me is

Can somebody help me here?.

I attempted to put the vectors as indicated in the drawing from below. But I don't know how to go from there?.

The figure from below describes a machine where a phone technician whose weight is $80N$ is standing over a flat platform which has a $30N$ of weight. If the system depicted is at equilibrium and the pulleys supporting the platform are of $10N$ each. Find the reaction modulus of the platform over the person.

$\begin{array}{ll}

1.&15N\\

2.&25N\\

3.&35N\\

4.&45N\\

5.&55N\\

\end{array}$

**how**should I understand the situation where the man is pulling through the cable which is connected to the platform which serves as the base for him to stand.Can somebody help me here?.
