What is the relationship between Moment of inertia and radius of gyration?
I believe it is I = mk^2 where k is radius of gyration and m is mass.
What is physical significance of radius of gyration?
Basically radius of gyration of a substance is defined as that distance from the axis of rotation from which if equivalent mass that of the substance is kept will have exactly the same moment of inertia about that axis of the substance.
Two spheres are cut from a certain uniform rock One has radius 4.15 cm The mass of the other is six times greater Find its radius?
Provided they are the same thickness, the larger sphere will have a radius of 10.165cm
How do you find mass of a sphere when only radius is given?
Volume of a sphere = 4/3*pi*radius3 Surface area of a sphere = 4*pi*radius2
if the earth had twice it’s present radius and twice it’s present mass, what would happen to your weight explain your answer?
i will be twice as heavy
THE MOMENT OF INERTIA OF A RING ABOUT ONE OF ITS DIAMETERIS L .ITS Moment of inertia about a tangent parallel to the diameter IS?
(1/2)mr^2 where m=mass r=radius
How do you derive the moment of inertia of solid sphere?
mass moment of inertia for a solid sphere: I = (2 /5) * mass * radius2 (mass in kg, radius in metres)
Moment of inertia of hollow cylinder?
The moment of inertia of a hollow cylinder can be calculated with the help of the formula, I=0.5xMxRxR. Here I is inertia, M is mass and R is the radius.
What is the relationship between Moment of inertia and radius of gyration?
I believe it is I = mk^2 where k is radius of gyration and m is mass.
Calculate the moment of inertia for a frisbee mass 0.40kg radius 12cm?
.00288 kgm^2
What is meant by Radius of gyration?
It is the square root of ratio moment of inertia of the given axis to its mass.
Why is moment of inertia of a solid disc smaller than that of a ring?
Moment of inertia depends upon the distribution of mass with respect to the axis of rotation.The greater the distance between the bulk of an object's mass and the axis of rotation, the greater the moment of inertia will be. A solid disk has its mass distributed evenly across its diameter, while a ring has its mass concentrated furthest from the centre of rotation.
What is the difference between mass moment of inertia and area moment of inertia?
mass moment of inertia is the property of the body to resist rotation about the given axis where as the area moment of inertia is the resistance to bending about the given axis
Mass moment of inertia of a disk?
Moment of Inertia of a disk (I) = 1/2MR2 Moment of Inertia of a disk (I) = 1/4MR2
What is the moment of inertia of a disk of radius 12cm and mass 2.4kg from whose edge a circular portion of radius 3cm has been cut off?
It can be done, but it would require taking an integral for the moment of inertia of each particle of the disc... something i don't have the time to do right now ^^;
What two quantities does rotational inertia depend?
mass, velocity and radius
What is moment of inertia of solid sphere about its diameter?
Rotated about a line on the surface ? I = Mass * radius2 . Rotated about a line through the centre : I = (2 * mass * radius2) / 5
