F В 30° F1 = 600N 1 a) Two ropes with force F and F1=600 N acting on the hook as shown in the figure. If a=120°, B<90°, y=60°, and F=400 N, determine the magnitude and coordinate direction angles of the resultant force acting on the hook. Answer: FR= N [5 marks] a=
B= = o [5 marks] y= O º [5 marks] b) If the resultant force acting on the hook is Fr= {-200i+800j+150k} N, determine the magnitude and coordinate direction angles of force F Answer: FR= N [5 marks] a= º [5 marks] B=
