How do new building tools impact the size and shape of buildings?
Cranes make a big impact. With cranes, we can build higher and sturdier buildings. The Greeks invented the crane around 500 B.C. The crane in the past only consisted of a winch and pulley. A simple winch is a spindle with a crank attached to it. A simple pulley is a wheel mounted on an axle. When these two devices were combined together, it created the ancient crane. If we didn’t have cranes, our buildings would be limited to what materials a few men could carry. We wouldn’t be able to make tall buildings like skyscrapers. Now we can build buildings that are over 500 meters high and have over 100 floors! For example, the Burj Khalifa, the tallest building in the world, is 828 meters high and has 163 floors!
As you can see, cranes impact the building’s size and shape.
