The **parallel** **axis** **theorem** **of** rod can be determined by finding the **moment** **of** **inertia** **of** rod. **Moment** **of** **inertia** **of** rod is given as: I = 1 3 M L 2 The distance between the end of the rod and its centre is given as: h = L 2 Therefore, the **parallel** **axis** **theorem** **of** the rod is: I c = 1 3 M L 2 - M ( L 2) 2 I c = 1 3 M L 2 - 1 4 M L 2 I c = 1 12 M L 2. **Moments** **of inertia** for the parts of the body can only be added when they are taken about the same **axis**. The **moments** **of inertia** in the table are generally listed relative to that shape's centroid though. Because each part has its own individual centroid coordinate, we cannot simply add these numbers. We will use something called the **Parallel** ....

How it works: The **parallel**-**axis** theorm states that if I cm I c m is the **moment**-**of-inertia** of an object about an **axis** through its center-of-mass, then I I, the **moment** **of inertia** about any **axis** **parallel** to that first one is given by I = I cm+md2 I = I c m + m d 2 where m m is the object's mass and d is the perpendicular distance between the two axes.. May 02, 2020 · The so-called **Parallel** Axes **Theorem** is given by the following equation: where I' is the **moment of inertia** in respect to an arbitrary **axis**, I the **moment of inertia** in respect to a centroidal **axis**, **parallel** to the first one, d the distance between the two **parallel** axes and A the area of the shape. Applying the above formula, for two **parallel** axes .... The **moment** **of inertia** of any object can be determined dynamically with the **Parallel Axis Theorem. Moment of Inertia Proof** Statement: The **moment** **of inertia** about Z-**axis** can be represented as: Where I cm is the **moment** **of inertia** of an object about its centre of mass m is the mass of an object r is the perpendicular distance between the two axes.. The **parallel axis theorem** can also be used to find a centroidal **moment** **of inertia** when you already know the **moment** **of inertia** of a shape about another **axis**, by using the **theorem** ‘backwards’, .
