please help! I need help finding and solving equations of
equilibrium to find the max tension in the cables and the angle
that results in the maximum tension, I also have pictures below of
the work I have so far all I really need is equations for the 4
cable part and that's it but I put the whole assignment so you
could see thanks!

find the LS and SS for the fit and the LH and SH for the hole.
Fits are all SHAFT BASIS METRIC but the shaft and hole diameters can not be used right out of the table. This is because the 3mm shaft tolerance does not match. You will need to lookup the "Fit" from the table, and then use the LS (Largest Shaft) and SS (Smallest Shaft)...
