Lifting cable danger. Cranes are used to lift steel beams at construction sites (Figure a). Let's look at the danger in such a lift for a beam with length L - 13.4 m, a square cross-section with edge length w = 0.588 m, and density p - 7900 kg/m . The main cable from the crane is attached to two short cables of length h - 7.00 m symmetrically attached to the beam at distance d from the midpoint (Figure b). (a) What is the tension Tran, in the main cable when the beam is lifted at constant speed? What is the tension T short in each short cable if dis (b) 1,60 m. (c) 4.24 m, and (d) 5.91 m? (e) Asd increases, what happens to the danger of the short cables snapping
