We should also learn about the moment of inertia of a circle which is given by the equation, Where R is the radius of the quarter circle and I is the moment of inertia. In a circle, the MOI of it about the x-axis is similar to that of the y-axis.īefore deriving the formula let us first have a look at the moment of inertia of a quarter circle which is given by the equation, The procedure for deriving the moment of inertia of a quarter circle is to find the moment of inertia of a circle and divide the result by two. To find the moment of inertia of a quarter circle about its centroid is similar to finding the moment of inertia of a circle. It is defined as the product of the particle’s mass in the object and its length’s square from the rotational axis. ![]() Indeed, the correct meaning of the angular momentum or the MOI is the tendency of an object to resist angular momentum. ![]() ![]() Whenever an object begins to rotate along a fixed axis, each component in the object moves in a circle with constant speed, indicating that each particle moves with rotational movement. It may be deduced that inertia is proportional to a body’s mass. First and foremost, let us define the idea of the moment of inertia in simple words.
