WebbI = mr². For a rigid body moving about a fixed axis, the laws of motion have the same form as those of rectilinear motion, with the moment of inertia replacing mass, angular replacing linear velocity, angular momentum replacing linear momentum, etc. Hence the kinetic energy of a body rotating about a fixed axis with angular velocity ω is ...

OTHER CALCULATORS AREA MOMENTS OF INERTIA BEAM CALCULATORS TORSION OF BARS CIRCULAR … 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. immersion heater schematic symbol
