PAD RV 8.4 diagram [311541]
The picture below shows a ladder leaned against a wall with a paint can sitting on it. Draw a force diagram for the ladder. Note that the top of the ladder has rollers so there is no friction between the wall and the ladder. Use the following to describe each type of force: "N" for normal forces, "Ff" for frictional forces, and "Fg" for forces of gravity. Always refer to the left hand surface as the "wall" and the bottom surface as the "ground", refer to the paint can as "paint". Be sure to name all vectors correctly using the scheme above. Also note that these names are case sensitive;so, use the provided names exactly as they appear.
