Question: 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)

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 A.

Given:
F1 = 80 lb c = 2 ft g = 4
F2 = 50 lb d = 4 ft θ = 30 deg
a = 1 ft e = 3 ft
b = 3 ft f = 3

F2 F1 +s -х

F2 F1 +s -
