For the reservoir at the top of the figure:

a) Determine the hydrostatic force and location of the center of pressure on the

chamfer (diagonal face) at the left end if it is 15 feet wide (the dimension into

and out of the screen/page), and determine the wall can safely support the force

if its maximum load is 3500 pounds per square foot.

b) Determine whether a hollow concrete block of 5' X 6' X 10' with a total

weight of 9500 pounds will float in the reservoir and, if so, how much of the

block will remain above the water surface. (Consider the likely orientation of

the block in the water.)
