Superelevation is the banking or tilting of a roadway on a curve to counteract the centrifugal force.

• Superelevation is used to increase the safety and comfort of vehicles traveling on curved roadways.

• It involves raising the outer edge of the road higher than the inner edge to create a sloping surface.

• The amount of superelevation required depends on factors such as design speed, curve radius, and vehicle characteristics...read more

Centrifugal force is the apparent force that acts outward on a body moving in a curved path.

• Centrifugal force is not a real force but rather a perceived force due to inertia.

• It is experienced when an object moves in a curved path and feels like it is being pushed away from the center of the curve.

• The magnitude of centrifugal force depends on the mass of the object, its velocity, and the radius of the curve.

• Centrifugal ...read more

Types of foundation include shallow, deep, and pile foundations.

• Shallow foundations are used when the soil is strong enough to support the structure's load, such as spread footings and mat foundations.

• Deep foundations are used when the soil is weak or unstable, such as pile foundations and drilled shafts.

• Pile foundations are deep foundations that transfer the load to deeper, more competent soil or rock layers, such as
