Sir, Please clarify two points. The reaction moment at A is 32.6 Nm. 1. if this reaction moment is due to reaction forces Fx and Fy ? if so, then reaction forces are passing through A and are not causing any moment at A, so how does moment Ma come, how to understand that ? 2. You said that Ma is a couple moment so which two equal forces are forming it ?? Thank you very much
@@engineeringdeciphered sir, reaction is due to an action. 52N and 30N are action forces, reaction moment should be having some forces causing it. Not able to grasp it. Could you please throw some light. Thank you. 🙏
@@shailkumarjain the reaction moment is caused by the wall. Those reactions at A are what the bar is feeling from the wall. If you are pulling down on the bar, the wall forces up on the bar. If you are trying to twist the bar, the wall has to twist back in the opposite way so that the bar stays in equilibrium. The wall has to be strong enough to counteract all those forces or the bar will move.

Good day sir. May you please reference me to a video where you go through how to determine the moments direction?
Thank you in advance.
Or not direction I mean whether it forms a clockwise or counter clockwise moment

The reaction moment is not due to Fx and Fy. It is counteracting (or summing to zero) the moments caused by the 52 and 30 N forces.
