Use the SPA$-$method!!!

Problem $2(12p)$ :

The principle behind pulleys is demonstrated using

the test setup in the figure.

Using the force $T$ and the pulleys, the block with a

mass of $500$ kg is kept in equilibrium.

Determine:

For this situation, calculate the magnitude of the

force I pulling the cable.

For this problem, you need to do the analysis,

planning and accomplishment of the SPA$-$

method.

The grade for this problem will be based on:

analysis of the load situation $(1$p$)$

correct FBDs $(5$p$)$

the equations of equilibrium needed $(4p)$

the solution itself $(2p)$
