Determine the magnitude F and direction (measured clockwise from the positive y-axis which is downward in this case) that will cause the resultant R of the four applied forces to be directed to the right with a magnitude of 12.4 kN. 11.1 kN 16.6 kN 36% 2L 60 Superscript The asymmetric simple truss is loaded as shown. Determine the reactions at A and D. Neglect the weight of the structure compared with the applied loads. Is the knowledge of the size of the structure necessary? 36 E 1L B A 3L 60 60 1 KN 30 1L D
