Mr. Kaminksi plans to dislodge a tree stump in his yard by using a 6-foot bar as a lever. He places the bar so that 0.5 foot extends from the fulcrum to the end of the bar under the tree stump. In the diagram, b represents the total length of the bar and t represents the portion of the bar beyond the fulcrum. a. Write an equation that can be used to calculate the mechanical advantage.
b. What is the mechanical advantage?
c. If a force of 200 pounds is applied to the end of the lever, what is the force placed on the tree stump?
