Oil of specific gravity 0.800 acts on a vertical triangular area whose apex is in the oil surface. The triangle is 9 ft high and 12 ft wide. A vertical rectangular area 8 ft high is attached to the 12-ft base of the triangle and is acted upon by water. Find the magnitude and position of the resultant force on the entire area.

Post-tensioned AASHTO Type III girders are to be used to
support a deck with unsupported span equal to 90 feet. One level
of Grade 270, 10 x 0.6" Ø 7-wire strand are used to tension the
girders. The girder is simply supported at both ends. The anchors
are located 2" from the neutral axis at the supports while the
eccentricity is measured at 14" at the midspan.
Use maximum values for ranges (table values).
The tendons are encased in flexible metal sheathing. Assume and
loadings are placed immediately after stressing.
Determine the stresses at the top and bottom of the beam,
including the stress at the level of steel after three years.
Given the following parameters:
F'c = 5000 psi
Fy = 240 ksi (Bonded, Stress-relieved)
Fu = 270 ksi
=
Es 29,000 ksi
Ec = 4,030 psi
Fj = 235 ksi
A = 1x0.6" 07-W.S. = 0.217 in²
Yc = 140 lbs/ft³
ΔΑ = 3/8"
RH = 33%
