# 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)
