... Just for fun, we will solve this one two ways: from the usual “laboratory frame” where we watch both blocks from the floor, and a frame of reference where block 2 is stationary. The latter is quite a bit less messy . . . but does require the foresight to think of it in the first place. Find: The cha ...

... But is the object necessarily in rotational equilibrium? Consider the case of a merry-go-round sitting on a frictionless surface. The only forces parallel to the surface are shown in the Figure. Obviously, the net horizontal force vanishes. What can you say about the angular acceleration around the ...

... However here we analyze the application of work concept in Mechanics. ‘Work’ has much more in it then just a language tool. For example, if a person is holding an object, he gets tired but still does no work. Here we will analyze such myths and also explore the term power. We will also gain an insig ...

Hunting oscillation
Hunting oscillation is a self-oscillation, usually unwanted, about an equilibrium. The expression came into use in the 19th century and describes how a system ""hunts"" for equilibrium. The expression is used to describe phenomena in such diverse fields as electronics, aviation, biology, and railway engineering.
