Engineering Mechanics Moments 2D

Hi, i just want to ask is there an easy way to master moment in 2d? It seems like moment 3d is much easier since you can use any points and connect them as line, 2d needs perpendicular lines so im having difficulties with it instead. Pls help.

Wow, you are awesome because most students are having difficulties in mastering the 3d even if they got a strong grasp in 2d.

For solving moment in 2d, you can actually resolve the 2d force into components at any point on its line of action. Choose a point that is in direct horizontal line or in direct vertical line of your moment center. In this way, you don't have to always find the perpendicular distance between the force and the moment center which is geometry intensive.
