You're too good i understood this in 16 mins❤

Awww thanks so so much

For question 1, why would the horizontal forces matter? Since they pass through the line of action they shouldn’t matter right

[@АдемаАбдрахманова]

hi, i still do not get when it is clockwise and when it is anticlock. hope u will see this.

[@SkanCityAcademy_SirJohn]

Well I get it, usually for moment. We focus on the force and the perpendicular distance. So you look at the line of direction of the force, and the perpendicular distance. For example 1. If the force is directed upwards, and the perpendicular distance is on the left of the force, then the direction is anticlockwise. 2. If the force is directed upwards, and the perpendicular distance is on the right of the force, then the direction is clockwise.

this is my solution of using moment of a couple anticlockwise: Mc = 0 anticlockwise Mc = 400(2) -200(0.2) - 300(5) Mc = -740 N/m clockwise is this considered as a correct answer?

[@SkanCityAcademy_SirJohn]

It's correct, except that you defined anticlockwise as negative, hence since you have a negative resultant moment, the moment should be anticlockwise and not clockwise. I hope you get it.

Excellent👏🏾

Thank you.

[@tiikis757]

isnt a clockwise rotation of a moment (-) while a clockwise rotation (+)?

[@SkanCityAcademy_SirJohn]

Kindly check your question

[@portiaaputerii768]

Thankssss

[@SkanCityAcademy_SirJohn]

Please you are most welcome

[@evansyuri3100]

Isnt the ccw (+) and cw(_) why did u made it positive sir?

[@SkanCityAcademy_SirJohn]

Kindly state the exact time in the video so I cross check for you.
