Quite lively here!
[Serious]I have actually heard of 'rolling g' before, in reference to an F14 Tomcat that was overstressed, yet did not show a max g above the limit on its g-meter. The pilot described how he did this, and referred to the dangers of rolling g several times.
Since the wingtips are being accelerated to a higher velocity (due to the rolling) than the fuselage in the same time period, they must experience a higher acceleration value. Quid pro quo. Cogito ergo sum. Q.E.D. And other Latin phrases.[/Serious]
Plus wheels ups quite correct reference to the force created by the difference in g due to the difference in distance from the earths centre of gravity, and we've got us some wing-ripping forces here! {please, somebody fall for this!}
