The 0.61 x 1.00 m lid ABCD of a storage bin is hinged on side AB and is held open by looping cord DEC over a frictionless hook at E (held open by forces DE and CE). A and B are level with the top of the bin (where the bottom of the lid meets the bin). If the tension in the cord is 75 N, determine a. The moment about A of the force CE. b. The resultant moment about A of the forces DE and CE. c. The resultant moment about each of the coordinate axes of the forces DE and CE. ** Note the orientation of the axes!
