Unbalanced Forces and Moments

Unbalanced forces create acceleration in the direction of the Net force.

Fy = my”

Which is the translational acceleration in the y direction

Unbalanced moments create acceleration in the direction of the Net moment/torque around a given axis, where α is the angular acceleration(rad/sec*sec),I – moment of Inertia(3X3).

τ = Iα

or if looking only at the y axis:

My = Iyφ
