A construction worker on a job site attempts to move a boulder out of the way by attempting to apply force F to a steel bar as shown. Unfortunately, his attempt at using the steel bar as a lever to move the boulder fails. He is not strong enough. The worker enlists a coworker to help him. The worker applies a force F₁ at point A and the coworker applies a parallel force F2 at point C. Calculate these two forces so that they will be equivalent to the single force F shown in the figure. Hint: For the two forces to be equivalent to the single force, they must give the system the same translation and rotation as the single force does.
