Problem 6.79
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.
