Normally, a plane moves along three rotational axes. “Inertia coupling” takes place when the plane inadvertently moves on two at the same time, usually resulting in loss of control.

In a state of bewilderment one fine day, I asked a group of three mechanical engineers at this company where I was then employed if they could please explain to me the concept of “moment of inertia”.

Figure 2: Degree of negative ambient gravity for (29075) 1950 DA. The free parameters to be constrained by the WISE observations in the model fitting include the diameter, thermal inertia, surface ...

(Phys.org)—Newton's gravitational constant, G, has been measured about a dozen times over the last 40 years, but the results have varied by much more than would be expected due to random and ...
