The moment of inertia of a ring about of its diameter is given by Id
ia=I=21MR2 where R= radius of ring
. Here, the distance between the tangent and the diameter is R. By parallel axis theorem
What is the formula for the moment of inertia of a ring?
The mass of the ring is m and its radius is R. What is the moment of inertia of the ring about its center?
I = mR2
. This is the same as the moment of inertia of a single body at distance R from the center.
What is the moment of inertia of a ring about its diameter?
Thus the moment of inertia of the ring about any of its diameter is
MR22
.
What is the diameter of moment of inertia?
Thus the moment of inertia of a disc about any of its diameter is
MR2/4
.
What is the moment of inertia of a ring disc?
Expression for the Moment of Inertia of an Annular Ring:
dI = 2 π t ρ r3
. dr . Where M is the total mass of the annular ring. This is an expression for moment of inertia of annular ring about a transverse axis passing through its centre.
What is the moment of inertia of a ring about a tangent?
We know that, moment of inertia of a ring about its diameter is MR2/2. Hence, the moment of inertia of a ring about a tangent in the plane of the circle of the ring is
3MR2/2
.
What will be the moment of inertia of a circle in CM 4 of diameter is 10cm?
What will be the moment of inertia of a circle in cm4 of diameter is 10cm? =
491.07 cm

.
What is the unit of moment of inertia?
The unit of moment of inertia is a composite unit of measure. In the International System (SI), m is expressed in kilograms and r in metres, with I (moment of inertia) having the dimension
kilogram-metre square
.
What is moment of inertia of solid sphere about its diameter?
Moment of a inertia of a sphere about its diameter is
2/5 MR2
.
Is i moment of inertia?
| Moment of inertia | Dimension M L 2 |
|---|
Which rolls faster a disk or a ring?
It is shown that the one that reaches the bottom first depends not on the mass or radius, but on the shape. To illustrate this further, a wooden disk, clad with a metal ring, rolls down faster than the hoop but slower than the wooden disk. and we see that the
disk rolls
faster and thus reaches the bottom first.
What is difference between ring and disc?
A solid disc and a ring will have
very different moments of inertia
due to the fact that the ring has all of its mass concentrated away from its center while the disc mass sone of its mass closer in.
What is the moment of inertia of a disc about one of its diameter?
1) In short the moment of inertia of a disc about its one of the diameters is equal to
the one-fourth of its moment of inertia about its
one of the axes.
What is the moment of inertia of a ring about its tangent parallel to the plane of the ring?
Therefore, the moment of inertia of ring about tangent in the plane of the ring is
3/2 MR
2
.
What is the rotational analog of mass?
Hint:
Moment of Inertia
is defined as the analogue of mass in rotational motion.
What will be the moment of inertia of a circle in of diameter is 20 cm?
a)
6852 cm
.
