A ladder leans up against a wall.
The top of the ladder touches the wall at a point 8 feet above the ground. In such problems the reaction forces also depend on the elasticity of the system and the way in which the system was set up. A ladder 13 meters long rests on horizontal ground and leans against a vertical wall. In the rst problem a ladder is leaning against a wall and sliding under the inuence of gravity alone.
