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