Supports at E and F are symmetric. Consider the location of the horizontal reaction at F at y=0. A = 1.8 m B = 1.4 m C= .8 m D=

E = F = .2 m This uneven C channel is supported by a hinge at F and a frictionless support at E. If the channel section has a weight of 10 N, what is the reaction at E and F? A horizontal force acting to the left is placed at the upper outer corner at C. The reaction at E is determined to be 1 N. What is the magnitude of the horizontal force at C and the resultant magnitude of the reaction at F?
