Solidworks Simulations I Hanging concrete slab

An L-shaped reinforced concrete slab 12 ft 12
ft (but with a 6 ft 6 ft cutout) and thickness t 9.0 in, is
lifted by three cables attached at O, B and D, as shown in
the figure. The cables are combined at point Q, which is
7.0 ft above the top of the slab and directly above the center
of mass at C. Each cable has an effective cross-sectional
area of Ae 0.12 in2
.
(a) Find the tensile force Ti ( 1, 2, 3) in each cable due
to the weight W of the concrete slab (ignore weight of cables)

what is the purpose of this simulation and what output we get from this can you say it
