Why passive earth pressure is greater than active earth pressure?

∙ 11y ago
The passive earth pressure occurs when when a wall or plane moves towards earth. This will create additional pressure where as in the case of active pressure wall moves away from earth and it will reduce the pressure on the wall. From the co-efficient of active earthpressure and passive earthpressure,i.e
Ka = 1-sin( phi)/1+sin( phi)
Kp = 1+sin( phi)/1-sin( phi where phi is the angle of internal friction of soil.

How much atmospheric pressure is exerted on one square inch of earth?
14.7 pounds. Atmospheric pressure is 14.7 pounds per square inch Keep in mind that unless air is trapped you do not feel this as pressure is equalized
How many times greater is the mass of Earth than the mass of an electron?
The mass of the Earth is about 6x1024 kg The mass of an elecron is 9x10-31 kg Divide the first by the second to get the answer: The Earth is about 6.5x1054 times more massive. 6,500,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000
What is 1543 copernicus's discovery led to greater understanding of the universe?
He said that sun was the center of the universe and that the earth and all the other planets orbit around it.
Which distance is greater The distance between the North and South poles The distance around the Tropic of Capricorn The distance around the Equator The distance around the Tropic of Cancer?
== == The perimeter of the equator is the greatest because the earth is a flattened sphere shape due to the influence of centrifugal force - a result of its rotation. The tropic of Cancer is slightly greater than the Tropic of Capricorn as there is a majority of continental land in the north. Land has a higher elevation than sea and to go around it you have to go to a higher elevation (radius) which means a greater perimeter. The north south distance is the least as it is a straight line.
Is the earth square?
No. The Earth is round!
What is the Difference between an active earth pressure and passive earth pressure?
When the wall moves away from the backfill, the earth pressure on the wall decreases. This minimum pressure is called active earth pressure. On the other hand if the wall moves towards the backfill, the earth pressure increases. This maximum pressure is called passive earth pressure.
How active satellite differ from passive explain with an example?
active satellites are receives the transmitted signal from earth ,amplify the signal and transmit it. it is also called as transponders. but passive satellites just receive and transmit the signal.itac as the reflector
How does the air pressure at the surface of the earth compare to the air pressure at about 7 miles above earth?
The greater the altitude, the lower the air prassure.
What happens to the temperature and pressure when descending into the Earth's interior?
the temp gets hotter and the pressure gets greater
How does pressure change as you go from the surface toward the center if the earth?
The pressure increases as you go deeper. The deeper you go the greater the pressure
How does pressure change as you go from the surface toward the center if earth?
The pressure increases as you go deeper. The deeper you go the greater the pressure
Basic Difference between Active and passive Satellite System?
An active satellite acts as a REPEATER; it amplifies signals received and then retransmits them back to earth. This increases signal strength at the receiving terminal to a higher level than would be available from a passive satellite. A passive satellite only reflects received radio signals back to earth. fr0m: ZIA UR REHMAN D-05-ES-29 DCET Karachi Pakistan.
Why does the inner core receive the greatest amount of pressure?
There is pressure within the earth due to the overlying material that the earth is formed from. The deeper within the earth you go, the greater the amount of overlying material pushing down due to gravity and so the greater the pressure. As the inner core has the largest amount of overlying material pushing down upon it, it experiences the greatest pressure.
How many more times is the atmospheric pressure in Jupiter's core greater than the atmospheric pressure at the earth's surface?
Earth's atmospheric pressure is measured as 1 bar. Jupiter's atmospheric pressure is 100 million bars. Therefore, it is 100 million times greater
Why is the pressure in the center of the earth greater than the pressure in the mantle?
Because towards the center of the earth, there is more mass on top of it, so there is more pressure. All of the other layers, and the stuff on top of the earth is pushing down on it from all sides. For the mantle, its only the stuff on the top of the earth that is putting pressure on it.
Why is the effect of westerlies felt greater in Europe?
the effect is felt to a greater extent because of the shifting of the pressure belts due to the coriolis effect ( shifting of the pressure belts because revolution of the earth around the sun ). hope that helps
What causes the speed of a tornado?
Most winds on earth are produced by pressure differences. The greater the pressure change over a given distance, the greater the wind speed. Tornadoes produce a large pressure drop over a very short distance, resulting in extremely high winds.
