Here is a list of the available calculation tools relative to the moment of inertia of a shape. More accurately, these tools calculate the second moment of area, which is a purely geometric property of a planar shape (not related to its mass). The second moment of area is commonly used in engineering disciplines, where by custom is called moment of inertia.

Get PriceThe moment of inertia of an object refers to a calculated measure for any given rigid body that's rotating around a fixed axis. Therefore, this measures the difficulty of changing the rotational speed of the object. It's possible to calculate this measurement based on the distribution of mass within the given object along with the position of the object's axis. This means that a single ...

Get PriceFor each joint, the moment of inertia is calculated by adding the products of each individual mass (m i) by the square of its respective length from the pivot (r i). Note that the equation for calculating the moment of inertia to consider for actuator N omits the mass of the actuator at the pivot point (N-1): Note: The equation used to calculate the moment of inertia above (in this case ...

Get PriceThe moment of inertia, otherwise known as the mass moment of inertia, angular mass or rotational inertia, of a rigid body is a quantity that determines the torque needed for a desired angular acceleration about a rotational axis; similar to how mass determines the force needed for a desired acceleration.It depends on the body's mass distribution and the axis chosen, with larger moments ...

Get PriceCalculate the moment of inertia of a disk that has a kinetic energy of 24,400 J when rotating 602 rev/min. The first step in solving this problem is to convert 602 rev/min to SI units. To do this, 602 rev/min has to be converted to rad/s. In one complete rotation of a circle is equal to 2π rad, which is one revolution and 60 seconds in a minute. Remember the units must cancel out to get rad/s ...

Get PriceWhile the actuator is operating, moment loads occur due to not only gravity, but also because of acceleration and deceleration of the load. Because moment loads can damage actuators, confirming that they are within specification is critical. However, calculating moment loads on linear actuators can be complicated and time consuming.

Get PriceCalculating moments of inertia is fairly simple if you only have to examine the orbital motion of small point-like objects, where all the mass is concentrated at one particular point at a given radius r. For instance, for a golf ball you're whirling around on a string, the moment of inertia depends on the radius of the circle the ball is spinning in: I = mr 2. Here, r is the radius of the ...

Get PriceFundamentally, power transmission is optimized in a mechanical system if the load inertia matches the motor inertia. This may, or may not be practically implemented with gearing between motor and load. Gearing inertia, inefficiency, mechanical limits, and cost all factor into the decision as to whether power transfer should be optimized. From a practical viewpoint, large inertia mismatches ...
