A W14x68 section of A992, Grade 50 steel, is used as a steel column with a total unbraced height of 12 ft. The column ends are both fixed. Determine the maximum axial LRFD safe load for this column
The following wind conditions are expected: V = 10 i - 5 j mph for 0 10 hr. Draw to scale the expected streakline of the stream for t = 3, 10, and 15 hr.
A drunk driver in a 2200kg car plows into a 2100kg parked car with its brake set. Police measurements show that the two cars skid together a distance of 28m before stopping.
The segment of river shown has a rectangular cross-section, with width 50 ft. The river bed is at angle theta=10 degrees from horizontal. The average velocity is 2 ft/s at the upstream end, and 3 ft/s at the downstream end.
The owners wish to achieve an initial acceleration from rest of 22 ft/(sec^2) on a level paved surface. What is the minimum coefficient of road adhesion needed to achieve this acceleration
Biota can uptake and bioconcentrate compounds through vapor phase absorption. For example, leaves exposed to elemental mercury vapors will absorb the mercury into the aqueous phase and the lipid phases of the leaves. Kow for mercury = 4.17.
A vertical curve is to connect two tangents that intersect at station 30+50 at an elevation of 800.00 ft. The approach gradient is 3 percent and the departure gradient is -5 percent. The elevation of the curve at station 32+50 must be equal to at ..
