Buildings

The Canadarm was developed by the National Research Council of Canada in collaboration with Canadian industry partners such as Spar Aerospace and the Canadian Space Agency. It was designed and built in Canada for use on NASA's Space Shuttle fleet.

Bus duct is generally preferred in high-rise buildings for its higher current-carrying capacity, lower voltage drop, and easier installation compared to traditional pipe and wire systems. Additionally, bus duct takes up less space, making it a more efficient choice for high-rise buildings with limited space for electrical distribution systems.

The Canadarm was developed in the early 1970s and took approximately five years to complete. It was officially tested in space in 1981 during a Space Shuttle mission.

You can know if your building is earthquake-resistant by checking if it was constructed following seismic building codes, using flexible materials, and having proper structural reinforcements like shear walls and braces. An evaluation by a structural engineer can also determine the building's earthquake resistance through a seismic assessment. Regular maintenance and retrofitting can help improve a building's earthquake resilience over time.

The Skylon Tower in Niagara Falls, Canada is a tall, cylindrical structure with a rotating observation deck at the top. It offers panoramic views of Niagara Falls and the surrounding area.

Lighthouse lights are typically white or red to help sailors determine their position and direction. Red lights are used to signify danger, mark a hazardous area, or indicate the port side of a ship. White lights, on the other hand, are more commonly used as a general guiding light for navigation.

One foot-candle is equal to the illumination produced by one candle from a distance of one foot away. It is a measure of illuminance used in lighting design and is equivalent to 10.76 lux in the metric system.

Construction of the Skylon Tower in Niagara Falls, Canada began in May 1964 and the tower was completed in late 1965. The total construction time was approximately 18 months.

The Space Needle's observation deck is located 520 feet above ground level.

The tallest redwood tree in the world is Hyperion, with an estimated height of over 380 feet (115.85 meters). It is located in a remote area of Redwood National Park in California.

The Space Needle in Seattle is 184 meters tall.

The tallest building in the world is the Burj Khalifa in Dubai, United Arab Emirates. It stands at 828 meters (2,717 feet) tall and has 163 floors.

The Great Wall of China is often cited as the only human-made structure that can be seen from the moon with the naked eye. However, this is a common misconception, as no human-made structures are visible from the moon. The only natural feature that can be seen from the moon is Earth itself.

The Great Wall of China is one of the few man-made structures that can be seen from space with the naked eye. Its long and winding structure spans thousands of miles across northern China.

The Eureka Tower in Melbourne is taller than the Sky Tower in Auckland. The Eureka Tower stands at 297 meters (975 feet) while the Sky Tower is 328 meters (1,076 feet) tall.

The antennas on the top of the Sears Tower were built to transmit television and radio signals. Being located at a height of over 1,450 feet, the antennas on the tower provide better signal reception and transmission capabilities due to less interference and higher line of sight.

The Sky Tower in Auckland, New Zealand took around two years to build, from 1994 to 1997. It was officially opened to the public on August 3, 1997.

Weathering can cause physical and chemical deterioration of building materials over time. For example, exposure to rain, wind, and temperature changes can lead to cracks, erosion, and discoloration. Chemical reactions from pollutants in the air can also weaken or corrode building materials.

Weathering can weaken building materials such as concrete, brick, and stone over time. Exposure to wind, rain, temperature fluctuations, and other elements can cause cracks, erosion, fading of paint, and deterioration of surfaces. This can lead to structural damage and the need for repairs or maintenance to prevent further degradation.

Earthquake proof buildings are not common worldwide due to the high costs associated with their construction. In areas with frequent earthquakes, like Japan and California, there is more incentive to invest in earthquake resistant technology. Additionally, building codes and regulations in these regions often require construction to meet certain seismic standards.

Triangular buildings are often considered more earthquake-resistant compared to other shapes due to their ability to evenly distribute seismic forces. Their structural stability and reinforced corners can help minimize damage during an earthquake. However, the overall earthquake resistance of a building depends on various factors, including the building materials, construction techniques, and foundation design.

The tallest building in Christchurch is the Grand Central Building, standing at 86 meters (282 feet) tall. It is located in the central business district of the city.

The highest building in Tbilisi is the Axis Towers, which consists of two connected skyscrapers reaching a height of 147 meters (482 feet).

It is technically feasible to create an artificial island out of concrete and build a city on it, as seen with projects like The Palm Islands in Dubai. However, there are significant environmental and engineering challenges to consider, including potential harm to marine life, the need for sustainable infrastructure, and the overall cost and feasibility of such a project. Additionally, careful planning and environmental impact assessments would be essential.

No, linear development and ribbon development are not the same. Linear development refers to a pattern of development where buildings are clustered along a main transportation route, while ribbon development is characterized by buildings extending as a continuous strip along a transportation corridor, typically resulting in a more spread-out development pattern.
