(Solved) : Two Couples Act On The Frame 3 . . .

Two couples act on the frame. Determine the resultant couple moment. Compute the result by resolving each force into x and y components and
(a) Finding the moment of each couple (Eq. 4 -13) and
(b) Summing the moments of all the force components about point B.

Given:
F1 = 80 lb d = 4ft
F2 = 50 lb e = 3 ft
a = 1 ft f = 3 ft
b = 3 ft g = 4 ft
