    Awesome little video, made solving my own personal mechanics problem very simple and I had watched quite a selection of other videos trying to find some guidance. Nice job 🤘

    I'm a bit confused. Why don't we multiply Nb by 9.6/2 when calculating the moment at point A? I thought that to find a moment, we need to multiply a force by its perpendicular distance divided by 2 (as taught in other videos)..? Someone please help

    2:56 should it be 9.6 or 4?

      9.6 is the perpendicular distance from the point of rotation (A) to the line of action of the force (Nb)

      We are not familiar with that expression.

    I have a question sir,,
    For ladders math, when I took (mg) for ladder, at an inclined plane.. then why we didn't take it's component like mgcos@ and mgsin@ ?

      Without seeing a picture, we cannot really answer the question satisfactorily. But for a force pushing against a sloped plane, you would want to calculate the two components (perpendicular and parallel to the slope). But for a ladder pushing against a vertical wall, there will only be a perpendicuar component when there is no friction and both horizontal and vertical components when there is friction.
