The **Moment of Inertia of a Cylinder about the Central Axis** calculator computes the moment of inertia of a solid circular cylinder of uniform density with radius a about the axis of the cylinder.

**INSTRUCTIONS:** Choose your preferred units and enter the following:

- (
**M**) This is the mass of the cylinder. - (
**a**) This is the radius of the cylinder.

**Moment of Inertial:** The calculator returns the moment of inertia (**MoI**) in kilogram-square meters. However, this can be automatically converted to other moment of inertia units via the pull-down menu.

**Lateral Surface Area (sides) of a Cylinder**based on height and radius.**Total Surface Area of a Cylinder**including the sides, top and bottom.**Volume of a Cylinder**based on cylinder height and radius**Cylinder Volume from Height and Circumference****Height of a Cylinder**based on the volume and radius.**Radius of a Cylinder**based on the volume and height.**Mass or Weight of a Cylinder**based on the volume and mean density of the cylinder.**Density of a cylinder**.**Lateral Surface Area of a Slanted Cylinder**.**Volume of a Slanted Cylinder**.**Weight or Mass of a Slanted Cylinder**.- Moment of Inertia of a cylinder shaped object based around the central axis
- Moment of Inertia of a cylinder shaped object around the end of the cylinder
- Moment of Inertia of a cylinder shaped object perpendicular to the central axis.
- Mean Density of Common substances (useful in calculating the mass/weight and the moments of inertia)
- Axial Stress on a Cylinder
- Tangential Stress in a Cylinder
- Tangential Stress outside a Cylinder
