Chec Before the trunk of a large tree is felled, cables AB and BC are attached as shown. Knowing that the tensions in cables AB and BC are 590 N and 695 N, respectively, determine the moment about O of the resultant force exerted on the tree by the cable at B. 6 m 0.75 m B E 4.25 m The moment about O of the resultant force exerted on the tree by the cables at B is N-m)i +( ON-m)j+ N-m)k.
