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.

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 F2₂ at point C. Calculate these two forces so that they will be equivalent to the single force F shown in the figure.
