The young tree was bent and has been brought into a vertical position by the three guy cables. If tension at AB = 0, AC = 10 lb, and AD = 15 lb. determine the force and moment acting at the trunk base point o. neglect the weight of the tree.

The young tree, originally bent, has been brought into the vertical position by adjusting the three guy-wire tensions to AB = 7 lb, AC = 8 lb, and AD = 10 lb. Determine the force and moment reactions at the trunk base point O. Neglect the weight of the tree.

C and D are 3.1' from the y axis B and C are 5.4' away from the x axis and A has a height of 5.2'
