42. A crane in a marble quarry is mounted on the quarry's rock walls and is support- ing a 2500-kg marble slab as shown in Fig. 12.26. The center of mass of the 830-kg boom is located one-third of the way from the pivot end of its 15-m length, as shown. Find the tension in the hor- izontal cable that supporte the boom.
