1. A crowbar lifts a weight in Fig. 10-21 below. A downward force on the long end of the crowbar, F₁, equals 225 N. How much weight must be held up by the upward force, F2, being exerted by the short end? The value of r₁-perpendicular is equal to 0.300 m and that of r₂-perpendicular is 0.0500 m. Ans. 1350 N upward.
