How to find the moment about a given line ( Vector Mechanics _ Beer Jhonston) Engineers Academy

In this video, we solve a mechanics/engineering mechanics problem where a cube of side a is acted upon by a force P. We determine the moment of P about:
Point A
Edge AB
Diagonal AG of the cube
And finally, we use the result to calculate the perpendicular distance between AG and FC.
This step-by-step solution covers important concepts of moments, vector approach, and perpendicular distance of a force from an axis — perfect for students preparing for engineering mechanics, GATE, ESE, IIT-JEE, and university exams.
