A control rod AB is fixed with a pin connection at B. The rod is 26 in long and is at an angle of 60 degrees from the positive x-axis. A 11.9 lb force F is applied to the end of the control rod (point A) down and to the right, at an angle of α from the rod. Knowing that it creates a 253.4 in lb clockwise moment about point B, determine angle α and the perpendicular distance between the line of action of force F and point B.

A control rod AB is fixed with a pin connection at B. The rod is 26 in long and is at an angle of 60 degrees from the positive x-axis. A 11.9 lb force F is applied to the end of the control rod (point A) down and to the right, at an angle of α from the rod. Knowing that it creates a 253.4 in lb clockwise moment about point B, determine angle α and the perpendicular distance between the line of action of force F and point B.
