In the figure below, water stands at depth D =30.0 mbehind the vertical upstreamface of a dam of width W = 320m.
(a) Find the net horizontal force on thedamfrom the gauge pressure of the water.
1 N
(b) Find the net torque due to that force (and thus gaugepressure)about a line through O parallel to the width ofthedam.
2 N·m
(c) Find the moment arm of this torque.
3 m
