A piece of machinery of weight W is temporarily supported by cables AB, AC, and ADE. Cable ADE is attached to the ring at A, passes over the pulley at D and back through the ring, and is attached to the support at E. Knowing that the tension in cable AB is 300 N, determine

(a) The tension in AC,

(b) The tension in ADE,

(c) The weight W. (Hint: The tension is the same in all portions of cable ADE.)
