The rectangular plate ABCD is held by hinges
along its edge AD and by the wire BE. If the tension in
the wire is 546 N, find the vector of this force? Express
in cartesian coordinates.
Using the vector approach, determine the moment
about A.
● Determine the moment about the axis AD of the
force exerted by the wire at point B?
