Calculate energy needed to bring the soil to surface level

Reference no: EM13324231

We are digging a hole to build a building. Calculate the energy needed to bring the soil to surface level. Remember the sides of the excavation lie at 45 degrees. Else, the whole would be constantly refilling itself.
Given,
density of soil= 140 lb/ft^3
The foundation is rectangular,
Breadth= 300'
width=30'
Depth=18'
Excavation includes 45 degree slope
CAT 329 Excavator
Bucket curling force(Fb)=45 Kip
stick crowd force(Fs)=30 kip
Bucket tip radius T=4'11''
Stick length(s)=6'
