Show that the system of forces represented by the lines joining any point to the angular points of a triangle is equivalent to the system represented by straight lines drawn from the same point to the middle points of the sides of the triangle
The Attempt at a Solution
i tried to find the resultant of the three forces which joint the point to the angular point and the three forces which join the point to the respective midpoints. i must get the same resultant i guess. but i didnt.
