Web2 Jul 2012 · You can sum moments about points A or B and get correct results only if you introduce the concept of a ficticious (pseudo) inertial force, P, where P = ma, applied through the object's center of mass horizontally in a direction opposite to the acceleration. This is what Andrien was hinting at. WebThe magnitude of the resultant moment can be calculated using the three-dimensional Pythagorean Theorem. 🔗 (4.5.4) (4.5.4) M = M = M x 2 + M y 2 + M z 2 🔗 🔗 It is important to avoid three common mistakes when setting up the cross product. 🔗 The order must always be , r × F, never . F × r.
