Shapes mlmebt of inertia
When a body is free to rotate around an axis, torque must be applied to change its angular momentum. The amount of torque needed to cause any given angular acceleration (the rate of change in angular velocity) is proportional to the moment of inertia of the body. Moments of inertia may be expressed in units of kilogram metre squared (kg·m ) in SI units and pound-foot-second squared (lbf·ft·s ) in imperial or US units. WebbThe Product Moment of Inertia is, by definition, zero for principal axes. Elastic Section Moduli: The elastic section moduli are equal to the second moments of area / moments of inertia divided by the distance to the farthest fibre in the cross-section perpendicular to the axis of bending.
