A farmer has to lift up a boulder 12 inches in the air in order to put it in his wagon. The boulder is 2000 bf. The farmer has the following tools available: a fixed pulley and a moveable pulley with a rope; an inclined plane with a length of 8 feet and a height of 12 inches; and a lever that is 10 feet long. The farmer has a maximum strength to push or pull 100 lbf.

Design a system using the tools the farmer has available to move or lift the boulder. Assume there is no friction and that mechanical advantage is ideal.

Calculate the ideal effort force that will be required by the farmer (must be less than 100 lbf)

Calculate the mechanical advantage of the individual mechanisms in the system and the total mechanical advantage of the system.
