Find the hydrostatic force of the plate shown below. (welwate!)

A force P of magnitude 90 lb is applied to member ACDE that is supported by a frictionless pin at D and by the cable ABE. Because the cable passes over a small pulley at B, the tension may be assumed to be the same in portions AB and BE of the cable. For the case when a = 3 in., determine (a) the tension in the cable, (b) the reaction at D.
