A crane boom of mass 450 kg with its center
of mass at C is stabilized by two cables AQ and BQ
(A_e = 304 mm² for each cable) as shown in the figure.
A load P 5 20 kN is supported at point D. The crane
boom lies in the y-z plane.
(a) Find the tension forces in each cable: T_AQ and T_BQ
(kN). Neglect the mass of the cables, but include
the mass of the boom in addition to load P.
(b) Find the average stress (σ) in each cable.
