What can engineers do to prevent structures from collapsing during earthquakes

Physics
1 answer:
vredina [299]3 years ago
3 0

Explanation:

1. The structures should be made with good quality steel and concrete so that they can bear load and deformation.

2. Buildings should be made laterally strong so that they can overcome dominant lateral forces.

3. In High seismic activity areas devices such as energy absorbers should be used. Base isolation must necessarily be done.

4. Use of hybrid Fiber Reinforced Concrete to increase the toughness of a structure in a Moment Resisting Frame. Moment resisting frames are frames that resist moment of any devices.

A girl picks up a bag of apples that are at rest on the floor. How dose the force the girl applies compare to the force of gravi
AysviL [449]

Answer:

When the bag of apples are on the floor, the force of gravity is equal to the force applied in the upward direction.

But when the girl picks up the bag of apples, she applies a force on the bag of apples in the upward direction greater than that of the gravitational force.

Explanation:

Gravitational force for an object is always constant at a specific point. When an object is in the state of rest, there is an equal force opposite to the direction of Gravitational Force.

Now, to lift an object upwards, an external force must be applied that is greater than the force of gravitation.

So, when the girl picks up the bag of apples,

Gravitational Force < Force applied by the girl to lift the bag.
