If an ellipse has a radius A long the x-axis and B along the y-axis (A > B) then the moment of inertia about the x-axis is 0.25*pi*ab^3

What is the value of moment of inertia of ellipse about x-Axis?

The moment of inertia of an ellipse about its major axis (x-axis) is given by the equation I = πab^3/4, where a is the length of the semi-major axis and b is the length of the semi-minor axis of the ellipse.


Is it possible for the moment of inertia to have a negative value?

No, the moment of inertia cannot have a negative value. It is always a non-negative quantity that represents an object's resistance to changes in its rotational motion.

How do you calculate moment of inertia of I-beam?

To calculate the moment of inertia of an I-beam, you need to know the dimensions of the beam (width, height, flange thickness, web thickness) and the material properties (density). Then you can use the formulas for moment of inertia of a beam to calculate the value. You can also use online calculators or software programs to help with the calculation.

What is the moment of inertia of a cube with uniform density about any edge?

Think of it as the difference in moment of inertias for two solid cubes. Calculate the moment of inertia of a solid cube with dimensions equal to the inner dimensions of your hollow cube. Then calculate the moment of inertia of a solid cube with dimensions equal to the outer dimensions of your hollow cube. Subtract the moment of inertia of the inner dimensions from the moment of inertia of the outer dimensions to get the moment of inertia of what's left. Same concept applies to finding the area of a thin-walled circle. Outer area - inner area = total area. Outer moment of inertia - inner moment of inertia = total moment of inertia. This approach won't work however if you're considering hollow shell - a cube with walls of zero thickness. If the axis of rotation goes through the cube center, perpendicular to one of its walls, first calculate moment of inertia of the wall that the axis passes through (let's call it Ia). For all equations below d equals surface density(mass per unit of area) and a is length of cube's side. Ia= d * a4 / 6 Then you have to calculate moments of inertia of four walls parallel to the axis. This will be Ib=4 * Iwall=4*d*a4/3. Total moment of the shell will be then: I=2*Ia+Ib=1.5*d*a4. If the axis is through the center and ┴ one face, I = (m/6)*[a² - (a-t)²], or I = (m/6)(2at - t²) for any value of t, however small. Source: CRC Std Math Tables


In the flywheel experiment how would you provide a value for the moment of inertia of a toothed gear wheel?

For flywheel: J= ?/32 × d4 ×?steel × lYou can obtain a more accurate value by considering every single component ie. each gear, each boss etcThe apparent moment of inertia is J'=J/R2R is gear ratio ,?steel is 8000 kgm3 and obviously d is diameter, l is length.. ..

How does the eccentricity of an ellipse change as the foci get closer together?

As the foci of an ellipse move closer together, the eccentricity of the ellipse decreases. Eccentricity is a measure of how elongated the ellipse is, defined as the ratio of the distance between the foci to the length of the major axis. When the foci are closer, the ellipse becomes more circular, resulting in a lower eccentricity value, approaching zero as the foci converge to a single point.


Does a marble roll faster than a person?

Yes, sometimes and no sometimes. In the case of rotating objects the more import value is moment of inertia. An object with a higher moment of inertia will accelerate slower (roll slower comparatively for any given time after release) down an inclined plane. In the case where the marbles are of equal diameter and uniform (although different if one is to have more mass) density the heavier marble will roll slower down a slope.


How does the numerical value of e change the shape of an ellipse?

The eccentricity of an ellipse, e, is the ratio of the distance between the foci to the length of the semi-major axis. As e increases from 0 to 1, the ellipse changes from a circle (e = 0) to form a more flat shape until, at e = 1, it is effectively a straight line.
