A 4 - (mathrm{ft}) by 3 - (mathrm{ft}) massless rectangular gate is used to close the end
Question:
A 4 - \(\mathrm{ft}\) by 3 - \(\mathrm{ft}\) massless rectangular gate is used to close the end of the water tank shown in Fig. P2.108. A 200-lb weight attached to the arm of the gate at a distance \(\ell\) from the frictionless hinge is just sufficient to keep the gate closed when the water depth is \(2 \mathrm{ft}\), that is, when the water fills the semicircular lower portion of the tank. If the water were deeper, the gate would open. Determine the distance \(\ell\).
