Extracted text: Two couple forces F = 67N, F - 61N, act on the frame and given that d- 4m and 0- 28". The other length parameters are a = 4m, b- 8m, C- 12m, and e- 12m. Compute the moment by the following methods: -F, -F1 F1 a) Find the moment of each couple by using cross product and add them up. M: kị N m b) Sum up the moments of all forces component about point B resolve forces into a and y components N- m
