O A water channel 12 feet wide is blocked by a rectangular barrier shown by member ABD.
Four supporting struts (member BC) are evenly spaced every 4 feet along the 12-foot width
of the barrier. The weight of barrier ABD is 200 lbs.
Assume the weight of the struts are negligible. The
specific weight of water is 62.4 lb/ft³. Determine the
magnitude of the force in each strut and state whether
the strut is in tension or compression.
