A 4-ft by 3-ft massless rectangular gate is used to close the end of the water tank shown in the figure below. A 200-lb weight attached to the arm of the gate at a distance from the frictionless hinge is just sufficient to keep the gate closed when the water depth is 2 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 & in feet. Hinge Hinge

Transcribed Image Text:A 4-ft by 3-ft massless rectangular gate is used to close the end of the water tank shown in the
figure below. A 200-lb weight attached to the arm of the gate at a distance from the frictionless
hinge is just sufficient to keep the gate closed when the water depth is 2 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 e in feet.
