What is gravity dam?
A gravity dam is a solid structure, made of concrete or masonry, constructed across a river to create a reservoir on its upstream. The section of the gravity dam is approximately triangular in shape, with its apex at its top and maximum width at bottom. The section is so proportioned that it resists the various forces acting on it by its own weight. Most of the gravity dams are solid, so that no bending stress is introduced at any point and hence, they are sometimes known as solid gravity dams
What is the force that causes the box to move downward?
Gravity because it is pulling down the box
What is the force that causes objects to have weight?
Gravity is the force that causes objects to have weight. Gravity is the attraction between two objects with mass, such as the Earth and an object on its surface, that causes objects to be pulled towards each other. The strength of gravity depends on the masses of the objects and the distance between them.
What force causes the ball to fall to the ground?
The force that causes the ball to fall to the ground is gravity. Gravity is a natural force that attracts objects towards each other, and in the case of the ball falling, it is being pulled towards the Earth's center by the force of gravity.
What force causes an object to have weight?
Gravity is the force that causes an object to have weight. The weight of an object is the gravitational force acting on it. The magnitude of the weight depends on the mass of the object and the acceleration due to gravity at that location.
When did McDonald Dam failure happen?
McDonald Dam failure happened in 1900.
What kind of dam is Hoover Dam?
It is an arch-gravity dam.
World largest gravity dam is located?
Three Gorges dam in China
Was the akosombo dam a success of a failure?
maybe
What is a masonry dam?
masonry dam is usually built by masonry that is basically stones,bricks and cement and in which the force that holds the dam in place against the push from the water is earth's gravity pulling down the mass of the dam

What does the concept of dam break refer to?
The concept of a dam breaking or dam failure refers to a breach in the dam structure. Such a breach can be catastrophic and the effects can be irreversible and may cause lose of life.
How do determine position of drainage gallery in a gravity dam?
Draingae
What are the relative advantages and disadvantages of the gravity dams over earth dams?
Advantage of a gravity dam is that every section will be stable and reliable. An Earth dam can overflow and collapse because of erosion.
What type of resource is the Hoover Dam?
Hoover Dam is what is called an arch-gravity dam. The name curved-gravity dam or arched dam might also be applied. This type of dam uses a curve or arch which has it's apex or "top" directed ''against'' the force of the water it is retaining. This sets up a condition wherein the water will compress the dam against the sides to which it is anchored. Less material fill is required to hold this dam in place compared to a simple gravity dam. Use the link below to learn more. Another link will show lots of images of this and other dams of the same type.
What was the worst engineering disaster in California?
