Question

Three forces FA =141 lbs, FB =212 lbs and FH =58 lbs are acting on the bracket shown with axes x,y,v and w indicated. If the angle measurements on the figure are c=7o , d=18o , f=9o and g=14o, determine the magnitude (lbs) of the resultant force.

FA NOTE: angles c, d, f, g, are not drawn to scale FH d X 00 W FB
