Actually the polygon direction is like a cyclic, see the direction of a' line, it is towards left side only. But while drawing i need to draw to line to get intersecting point., so I draw towards rightside and Mention the Direction towards leftside. If all the values are known, we can draw as per the direction. But when the values are unknown, we should know the proper direction and mark them after completing the lines.
Form reference plane diagram it seems correct sir that A is lying in negative side from B and D is lying in Positive side from B then why should we change the position in reference plane diagram and also in couple polygon diagram initialy why you taking A in right side sir if we taken along D it will intersect sir 27:49
According to polygon law, the closing side and opposite direction to the cylce is resultant. Cycle of couple polygon is anticloskwise and we draw A clockwise as closing side.
@@focusacademylectures sir according to force polygon A is in downward direction and you drawn it in reference plane with A facing downward direction but why in couple polygon we took A in upward instead of Downward facing😞
Force polygon was drawn to the balanced forces., Which form a cycle. There will be more complications, better yu solve more problems then u can get things better.
Sir couple polygon diagram la ethunala d ah c point la irunthum, a point ah O point la irunthum eduthinga? And d & a point ah downward la thana sir iruku... Namalum athe mathiriye draw pannalum interacting aagume sir... Please clear my dount sir.. Tomorrow morning exam
Sir at 28:29 , The angle of A is 236° So, it will be in third quadrant from O and both D and A will intersect in third quadrant sir? If I am wrong pls correct me sir.
In couple polygon why shoud u take a' line in right side in angular position it is in left side direction ?

Initially we assumed., After finding the values we correctour initial assumptions.

Each masses in different planes, there ll be no intersection.
