A 10 m ladder of 150N is placed at an angle 30degrees to a smooth wall at point A and the other end (point B) on the ground. Assume that the weight of the ladder acts at its mid point and there are two forces R and F that act on the ladder so that it is in eqilibrium.
Find a vector that represents the moment about point B that is due to the weight of the ladder.
