Pulleys are used for drawing water from a well. A crane uses a pulley to lift heavy loads. An elevator uses a pulley to lift people. It uses a counterweight on the the other end to do this. This simple machine is put to numerous applications in our daily world, though mostly not in ...
Photo: The pulley wheels and hook on a large crane. Any weight dangling from the bottom of this hook will be supported by the 16 lengths of wire rope above it. The more lengths of rope wrapped around a pulley wheel, the easier it is to lift. Photo by Jet Lowe, Historic American Engi...
This arrangement of a grooved wheel along with a rope or a chain is also a simple machine and is known as a pulley. Single movable pulley. A single movable pulley is able to move over the rope through the groove. Its axis of rotation is not fixed. One end of the rope is fixed ...
If you want to lift a really heavy weight, there’s only so much force your muscles can supply, even if you are the world’s strongest person. But use a simple machine like a pulley to multiply the force your body produces. The object lifted by a pulley is called the load. The fo...
Levers can be found everywhere and have been used since ancient times. But why do we use them and what is the science behind how they work?
Many complicated inventions can be broken down into a few of the six simple machines: the lever, inclined plane, wheel and axle, screw, wedge and pulley. These six machines form the basis for many more complicated creations that help to make life easier. Many students are required to create...

Amazon SageMaker AI Random Cut Forest (RCF) is an unsupervised algorithm for detecting anomalous data points within a dataset. These are observations which diverge from otherwise well-structured or patterned data. Anomalies can manifest as unexpected spi
In the Hello World application from last month’s column, the code had exactly one component—the AppComponent—which provided a simple, non-interactive text display greeting the world. Despite its simplicity, it was and is a full-blooded Angular component, as evidenced by t...
