# Mass moment of inertia of a Cylinder

Calculates the mass moment of inertia of a solid Cylinder.

`I_z = 1/2*m*R^2` (about central axis)

`I_x=I_y = 1/4*m*R^2+1/12*m*h^2` (about diameter)**Enter 'x' in the field to be calculated.**

This tool calculates the mass moment of inertia of a solid cylinder.

Case of a rotation about the central axis (z-axis on above diagram),

`I_z = 1/2*m * R^2`

Case of a rotation about a diameter (x-axis or y-axis on above diagram),

`I_x = I_y = 1/4*m * R^2+1/12*m*h^2`

m : mass of the cylinder (kg)

R : radius in meter (m)

h : height in meter (m)
