Understand tension forces through a fun superhero rope problem. This video uses a real-world–inspired scenario to explain how tension acts in a rope, how forces are distributed, and how Newton’s Laws ...

My recent post on tightropes reminded me of a great "hack." Here's the situation. Your car is stuck in the mud, so you grab a rope and tie it to the front of the car and then the other end to a very ...

Check out this video demo: So, that is just plain water. If I am careful, I can make that thin aluminum disk stay on the surface of the water. This is not the same as floating in Archimedes principle.

While most of biology and medicine focus on the key roles genes and chemicals play in living systems, the spatial arrangement of the components that make up those systems and the physical forces they ...

Organ development in the embryo requires precise coordination and timing of cell growth in three-dimensional space to produce the correct anatomic form and shape. Researchers at Children's Hospital ...

When webs of continuous paper, wire, cloth, or plastic are manufactured, the material is typically pulled off a roll, processed, and rewound in unwind, intermediate, and rewind zones. Knowing the ...

The goal of mechanobiology is to develop a mechanical description of cells and their parts. Platelet clotting, for example, is an important biological process that can only be fully understood if a ...

During manufacturing or converting processes, material is generally pulled off a roll, processed, and rewound — in sections called unwind, intermediate, and rewind zones, respectively. Knowing the ...
