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 ...

1.1 What is friction? Take this everyday example: when a coffee mug rests on a flat table, the kinetic frictional force is zero. There is no force trying to move the mug across the table, so there is ...

Keywords: Seismic performance. Nonstructural components. Static friction coefficient. Kinetic friction coefficient. Rigid blocks. Block-type components. Tilt and pull tests. Dynamic analyses.

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

You've got the golden armadillo? Quick, go before the dragon catches you! It could be here any minute – why aren’t you moving faster? Friction? You mean the force between the surface of the road and ...

The finding could eventually lead to robotic snakes that move more naturally claims David Hu, a mechanical engineer at Georgia Tech, who has been studying snakes to learn above their movement. "When I ...
