In the moment calculation of a given force F around a point P in the space, the coordinates of point P is (3,4,1) ft, the coordinates of F is (1i,6. -5) th, 2 r zak ef F in (4i+4j+7k)lbe and the resulted moment is (38i87j+28k) lbf f. Calculate the normal distance from point p to the line of action of the given firce 1.75ft 1.1ft 11ft 4. 15 ft
