Question:

The rig shown consists of a 5.4-kN horizontal member ABC and a vertical member DBE welded together at B. The rig is being used to raise a 16.2-kN crate at a distance x = 4.8 m from the vertical member DBE. If the tension in the cable is 18kN, determine the reaction at E assuming that the cable is

(a) Anchored at F as shown in the figure,

(b) Attached to the vertical member at a point located 0.4 m above E.

1.5m -7 m 2m -26 m- W=34 KN
