They use:
Dirt, Mud, Stone and other natural materials them.
Resistant materials are those that are strong and stiff, such as metals, wood, and ceramics. They can withstand a lot of stress without breaking or bending. Compliant materials, on the other hand, are soft and flexible, such as rubber, foam, and fabric. They can easily be bent or deformed, but they will return to their original shape when the stress is removed.
A compliant material is a material that conforms to regulations or even a building code. It is a material that has recognised, predictable and consistent properties. A material is a compliant material, if it conforms to a known performance criteria.
The 4 main forces of flight are: drag, thrust, lift and weight
this is the stupidest website in the world i cant find any awnsers anywhere
The origin of hacking and privacy compromise started before computers were invented. Military armed forces used a type of hacking to gather intelligence from military papers. The invention of the computer was really a way to try and decipher the codes sent from enemy forces during World War II.
yay! :)
composite material which mean a combination of material.
Torsional strength describes a material's ability to withstand twisting forces. It is an important property for materials used in applications where twisting or torque forces are applied.
Not clear what you're asking, but clearly strong materials are needed when there are strong forces that must be withstood. And things that must withstand strong forces include, but are not limited to: Large skyscraper buildings where their weights are strong forces on their frames and foundations, where strong materials (e.g., steel and rebar cement) are used. Hydro-electric dams where the weight of the backed-up (dammed) water pushes forcefully against them and strong materials are needed to prevent the dams from collapsing. Aircraft where aerodynamic forces lift and sustain the planes in the air and the materials must also withstand in impact of airflow as they move near the speed of sound through the air. These must be strong for sure, but they must also be light weight so they can be lifted into the air.
A material's ability to withstand cutting is described by its resistance to deformation and fracture under applied forces. This is typically characterized by properties like hardness, toughness, and tensile strength. Materials with high hardness and toughness are generally more resistant to cutting forces.
Tinsile strength
Buildings are generally best equipped to withstand lateral shaking, as they are designed to resist forces pushing horizontally. However, vertical shaking can also cause damage, particularly in taller buildings or those with poor foundation. The ability of a building to withstand shaking depends on its design, materials used, and structural integrity.
Structures and devices are designed to withstand various forces, such as gravity, wind, earthquakes, and other environmental conditions. Engineers use mathematical calculations and simulations to ensure that structures can withstand these forces and remain safe and stable over their lifespan.
Rockets are primarily made from lightweight yet strong materials such as aluminum, titanium, and composite materials like carbon fiber. These materials are carefully designed to withstand the high pressures, temperatures, and forces experienced during launch and space travel.
Base isolation pads can be built to absorb the vibrations to withstand earthquakes. Building materials can be reinforced to withstand an earthquake. For example, wood can be reinforced with bolts to make the wood more secure.
Central African Armed Forces was created in 1960.
Tension forces pull materials apart, while compression forces push them together. Tension can cause stretching and weakening, while compression can cause crushing and buckling. Both forces can affect the structural integrity of a material by causing deformation or failure if the material cannot withstand the applied forces.
