The law of rotational dynamics states that the moment of inertia times the angular acceleration equals the applied torque. This is analogous to the 2nd Newton’s law. But can the former be logically deduced from the latter? The rotational law… Read More
Traditionally, Mechanics is divided into three parts: the Statics (a study of forces without regard of motion), Kinematics (a study of motion regardless forces), and Dynamics (the study of forces and motions in combination). Well, this is a continental classification,… Read More
There is a wide-spread misconception about Newton’s laws of motion. Many people believe that all mechanics can be deduced logically from Newton’s laws in a manner similar to how geometry can be deduced from Euclid’s axioms. This is incorrect. By… Read More
Some people state that mechanics is not a fundamental science, but rather an applied discipline. I belong to a school of mechanicians, who would strongly disagree with that assertion. For me, mechanics is a part of physics; however, it has… Read More
Про трение как “сопутствующее явление” (“Friction as an epiphenomenon”) is a bit “philosophical” paper in Russian about friction. For most conventional textbooks on mechanics, Coulomb’s dry friction is an external phenomenon, which is introduced in an ad hoc manner in addition… Read More
