Q1) The roof shown in Fig 1 is hanged to the Wall at the angle at A by two cables AB and AC. If the value of F1= 150 N and F2 -200 N are the forces in cable AB and AC respectively, express F1 and F2 vectors in Cartesian form. Then compute the resultant of the two force vectors and express it in Cartesian form. Also calculate the directions angles of the resultant force. (40 points) 4m 2m 2m Fig. 1
