Sometimes you think you have a complete understanding of something and then BOOM—a simple problem throws everything out the window. Let's consider a very basic physics problem involving pushing a ...

In this video, we break down the classic physics problem of a block on an incline with friction. Learn how to calculate the forces at play, including gravitational force, normal force, and frictional ...

In today's episode, Shini tells us about Static and Kinetic friction. Why is it hard to move a heavy bookcase across a carpeted floor? And why is it easier to keep it moving than it was to get it ...

Humans have been making fire using friction for thousands of years, with evidence of its use found in archaeological records across different cultures worldwide. Fire by friction is a testament to ...

To gain more confidence with FEA, it’s a good idea to first solve simple problems with pencil and paper. Many less-experienced users of finite-element-analysis (FEA) software often have no clue if the ...
