What friction rate should we use when designing a residential duct system? is 0.1” of water column safe? When it comes to understanding friction rate in residential ductwork design, Allison Bailes III ...

Really, this is the experiment I wanted to start on. How does friction work in Bad Piggies? Let me start with a quick summary of my experiments so far. Scale. For the size of stuff in Bad Piggies, I ...

Show that static friction is greater than kinetic friction by pulling on a wooden box using a spring scale. Clamp the board to a table. (Optional) Select the 50 N scale on the force probe and connect ...

Most people have experienced the hair-raising effect of rubbing a balloon on their head or the subtle spark caused by dragging socked feet across the carpet. Although these experiences are common, a ...

Say we consider a simple experiment of balancing a wooden rod on two fingers. The finger on the left, (1), will remain stationary, whereas the finger on the right, (2), will be moved toward the left.

A future iPhone or iPad may provide users with more touch-centric haptic feedback, by using electrostatic layers to create points of friction on the display that a user could sense with their finger.
