A crane boom 10 m long, weighing 870 N and having its center of gravity 3 m from the bottom, is hinged at the lower end and makes an angle of 30° with the vertical. It is held in position by a horizontal cable fastened at the upper end. The boom supports a 4350-N load at its upper end. Find the tension in the cable. (Hint: Use the bottom end of the crane as the moment center. A correct diagram will receive credits)
