Tilting (Edexcel A-Level Mathematics): Flashcards

Unbalanced moments from external forces cause the tilt.

Moment = Force $\times$ Perpendicular Distance from the Pivot.

It's the average position of all mass in the object.

It may decrease to zero at the edge that starts tilting.

Resultant force's line of action must exit the base support.

When applied force moment equals the weight moment.

Moment = Applied force $F$ × Height $h$.

$F \times h \geq mg \times (w/2)$ for tilting to occur.

$F \geq \frac{mg \times (w/2)}{h}$ for box to start tilting.

Lower centre of mass, widen base, or add weight.
