It's perhaps the second week of your introductory physics course. Your instructor starts talking about friction and writes the following two formulas on the board. Then there is probably some sort of ...

Do you need some practice with force diagrams for your introductory (or advanced) physics course? Here are three questions (and the last one is awesome) about the motion of a bike as it is pulled.

This video is an introduction to shear force and bending moment diagrams. What are Shear Forces and Bending Moments? Shear forces and bending moments are resultants which are used to conveniently ...

THIS is a reprint in book-form, with additions, of a series of articles which appeared in Engineering in the autumn of 1906. Those who have had any experience of such work will know how tedious is the ...

We are getting closer to understanding when the strong nuclear force loosens its grip on the most basic constituents of matter, letting quarks and gluons inside particles abruptly turn into a hot ...
