Two couple forces F1 = 68N and F2 = 70N act on the frame. Given that d = 6m, 0 = 33 , a = 2m, b = 4m, c = 6m, and e = 6m, resolve the forces into x and y components and compute the moment by using the following methods: b e 0F2 B 2 C E F 2 5 3 F1 4 2 G un F1 A X a) Finding the resultant moment of both moment couples. M: i + j + k ) N . m b) Summing the moments of all force components about point B. MB: N . m
