Why did you put this on here when you know the answer lol
Answer:
The effective stress is 225.6 kN/m²
The total vertical stress is 338.4 kN/m²
Explanation:
Given;
depth of soil surface = 6m
weight unit of the soil samples = 18.8 kN/m³
Stress = force/area
Stress = unit weight x depth
Effective stress at a depth of 12 m below the soil surface:
= (18.8 kN/m³) x (12 m)
= 225.6 kN/m²
Effective stress = 225.6 kN/m²
Total vertical stress at a depth of 12 m below the soil surface:
= (18.8 kN/m³) x (6 m) + (18.8 kN/m³) x (12 m)
= 112.8 kN/m² + 225.6 kN/m²
= 338.4 kN/m²
Total vertical stress = 338.4 kN/m²
Answer:
Potential energy.
Explanation:
Potential energy, stored energy that depends upon the relative position of various parts of a system. A spring has more potential energy when it is compressed or stretched. A steel ball has more potential energy raised above the ground than it has after falling to Earth.
I hope this helps have a great day :)
Answer: No fundamental difference
Explanation: There is no fundamental difference between nano-composite and conventional composites. Conventional composite have a particular structure similar like the nano- composite material which have a composition of the nano-crystals.They both have a hardness to some extent and also face damage under extensive load impact. Thus , they have certain difference but that can't be considered as the primary or fundamental.
