The upper
edge of a gate in a dam runs along the
water surface. The gate is 2.00 m high
and 4.00 m wide and is hinged along
a horizontal line through its center

about the hinge arising from the force
due to the water. (Hint: Use a procedure
similar to that used in Problem
12.55; calculate the torque on a thin, horizontal strip at a depth h and
integrate this over the gate.)
