What is the definition of abutments?
Abutments are supporting structures that bear the load of a bridge or similar construction at the points where it meets the ground or other structures. They transfer the weight of the structure and any loads placed on it to the ground below, helping to stabilize and distribute the forces involved.
Why did the Aztecs build pyramids?
The Aztecs built pyramids for religious and ceremonial purposes, as well as to serve as platforms for the performance of rituals and sacrifices. They believed that the pyramids connected them to the gods and the spiritual world, and that by building and performing ceremonies on them, they could maintain harmony with the divine forces.
What is the headline for acre 1189-1192?
The headlines for Acre from 1189-1192 would likely focus on the Siege of Acre during the Third Crusade, detailing the events of the conflict and the battles between Christian and Muslim forces for control of the city. Additionally, headlines might cover key figures involved, such as Richard the Lionheart and Saladin, and any significant developments or alliances that shaped the outcome of the siege.
What were the motivating forces for the European exploration?
The main motivating forces for European exploration were the desire to find new trade routes to Asia, the search for valuable resources like gold and spices, the spread of Christianity, and competition among European powers to establish colonies and expand their empires.
Why did the Aztecs build there city in in the middle of a swamp?
The Aztecs built their city, Tenochtitlan, in the middle of a swampy area because it provided natural defenses against potential enemies. The marshy terrain made it difficult for invading forces to approach the city, as they would have to navigate through the waterlogged land. Additionally, building on the marsh allowed the Aztecs to control water resources and establish control over the area.
What forces is applied in pole vault pole?
The forces and energy involved consist of speed/velocity, gravity and kinetic energy.
What are the forces involved in a trebuchet?
Thurst, Gravitiy, Potential Energy, Kinetic Energy, and a few other.
The source of energy for constructive forces such as mountain building is Earth's internal?
heat
How is nuclear energy the same from other form of energy?
It is especially comparable to chemical energy, in that it involves forces between particles, and the corresponding potential energy. However, the forces between nucleons (protons and neutrons) for nuclear energy are much, much greater than the chemical forces between atoms, and the corresponding energies involved are therefore much greater.
How is energy involved in state changes?
Energy is involved in state changes as it either needs to be added or removed to break or form intermolecular forces between particles. For example, when a solid transitions to a liquid phase, energy must be added to break the bonds holding the particles together. Conversely, when a gas condenses to a liquid, energy is released as the particles come together and form intermolecular forces.
What type of forces are acting on flying buttress?
Flying buttresses experience compression forces from the weight of the building they support and tension forces from the forces exerted by the building pushing against them. These forces work together to stabilize and support the walls of the building.
What type of energy is it when you are breaking sticks?
Mechanical energy is involved when breaking sticks, as the force is applied to overcome the internal forces holding the stick together. This mechanical energy is converted into kinetic and potential energy as the stick breaks.
What are some forces in building a building?
compresive force
How is energy involved when substances change state?
When substances change state, energy is either absorbed or released. During melting and boiling, energy is absorbed to break the intermolecular forces holding the substance together, while during freezing and condensation, energy is released as these forces are formed. This energy change is due to the breaking or forming of bonds between molecules.
A type of building that absorbs the energy of seismic waves is a fixed-base building true or false?
False. A type of building that absorbs the energy of seismic waves is typically referred to as a base-isolated building, not a fixed-base building. Base isolation involves the use of flexible bearings or isolators that allow the building to move independently from ground motion, reducing seismic forces. In contrast, fixed-base buildings are rigidly anchored to their foundations and do not have this energy-absorbing capability.
What are the names of the forces involved in flying paper airplanes?
Lift, weight, drag, skill and luck (to give it the right amout of kinetic energy).
If you Add up the total kinetic energy and potential energy what does that give you?
The sum of potential and kinetic energy gives you the Mechanical Energy of the system
