A certain force F has a moment of 18Q N-m clockwise about point O and 9T N-m counterclockwise about point B. If its moment about point A is zero, determine the magnitude and direction of the force. Also, determine the x-intercept of the force. (x-intercept of the force is the distance of the intersection of the line of action of the force and the x-axis, measured from the origin O).

Wherein:

Q=2

T=6

Example:

2QT kN = 226 kN

T.Q5 m = 4.25 m

PROBLEM NO. 1
A certain force F has a moment of 18Q N-m clockwise
about point O and 9T N-m counterclockwise about point
B. If its moment about point A is zero, determine the
magnitude and direction of the force. Also, determine
the x-intercept of the force. (x-intercept of the force is
the distance of the intersection of the line of action of
the force and the x-axis, measured from the origin O)
