Problem 2 The 75-pound rectangular plate ABCD is held in the horizontal position shown by cable EF and by hinges at A and B. There is no y-component of the force exerted by the hinge B on the plate. The hinges are perfectly aligned; therefore, no moment is exerted on the plate by either hinge. Note that hinges A and B are offset from the plate edges by 4 inches; and point F is directly above the corner of the plate. a) Determine the reaction forces that hinges A and B exert on the plate and report these answers in cartesian form. b) Determine the magnitude of the tension force in the cable EF. 30 in E 8 in 20 in 25 in

Transcribed Image Text:Problem 2
The 75-pound rectangular plate ABCD is held in
the horizontal position shown by cable EF and by
hinges at A and B. There is no y-component of the
force exerted by the hinge B on the plate. The
hinges are perfectly aligned; therefore, no moment
is exerted on the plate by either hinge. Note that
hinges A and B are offset from the plate edges by 4
inches; and point F is directly above the corner of
the plate.
a) Determine the reaction forces that hinges A
and B exert on the plate and report these
answers in cartesian form.
b) Determine the magnitude of the tension.
force in the cable EF.
