Q2) A trapezoidal wadi 3 m wide and 2:1 side slope is to cross a road at station 1+120. The drainage area is 50-hectare consisting of bare earth with steep slopes. A concrete box culvert is considered to drain the wadi assuming 15 minutes concentration-time and a 20-years return period.
Determine the minimum width of the culvert to the nearest 10 cm assuming one meter maximum culvert depth, two meter allowable headwater depth, 1% culvert slope (same as the Wadi slope at the area), 25 m culvert length and squared culvert edges with headwall parallel to the embankment

An engineer is required to survey a nonrectangular plot of land but is unable to measure side UT directly due to a water obstruction. The following data are taken: RU = 130 m, RS = 120 m, ST = 91 m, angle RST = 115º, and angle RUT = 100º. Calculate the length of side UT and the area of the plot.

STEEL STRUCTURES

A 20ft long simply supported beam is made of W21X55 with fy=50ksi. The service distributed loads on the beam are DL=2k/ft (including self weight), LL=4 k/ft. Show if the beam is adequate for shear.

I need information regarding fatigue cracking and block cracking in flexible pavements, information should include but not limited to ; causes, severity levels,measurement methods, maintenance procedures and preventive measures.

please write 3 or more references.

Thank you!

1. A new entrance road to the pump station will be constructed using crushed stone. The road is 675’ long, 27’ wide, and 18” thick. The road will be constructed using a dozer and self-propelled tamping foot roller. The dozer has a power-shit transmission and a rated blade capacity of 6 LCY and pushing a distance of 100 feet per cycle. Maximum reverse speed is 4 MPH. It will spread the rock in 6” lifts. The compactor will follow each spreading lift with 3 passes. The compactor width is 6 feet and speed per pass is 1.5 MPH. Job efficiency is assumed to be 50 minutes per hour for both operations.  How much crushed stone (rock) is required? (LCY)  How long will it take to spread the rock? (Hours)  How long should it take to compact the rock?(Hours)

idk we werent given that info

what is cradle to grave, grave to the gate boundary and define each steps with an example
