A soil weighs 2,520 lbs/CY in its in situ condition, 1,970 lb/CY in its loose condition after excavation, and 3,025 lbs/CY in an embanked state. Compute the Load Factor and Shrink Factor for this material.
How many truckloads hauling an average volume of 16 LCY would be required to haul 1 million CCY of the soil from a borrow pit to a dam site?

Respuesta :

Answer:

load factor = 0.782

Shrink Factor = 0.833

no of truck is  62500

Explanation:

given data

soil weighs in situ condition  =  2,520 lbs/CY

soil weighs in loose condition  =  1,970 lb/CY

soil weighs in embanked state = 3,025 lbs/CY

average volume = 16 LCY

soil from a borrow pit = 1 million CCY

solution

first we get here Load Factor that is express as

load factor = [tex]\frac{1,970}{2550}[/tex]

load factor = 0.782

and Shrink Factor will be as

Shrink Factor = [tex]\frac{2520}{3025}[/tex]

Shrink Factor = 0.833

and

no of truck will be

no of truck = [tex]\frac{1000000}{16}[/tex]

no of truck is  62500
