What is the unit of moment of inertia in MM?

One gram square millimeter is equal to the moment of inertia of a single particle having the mass of one gram rotating at one millimeter distance from the rotation axis. A kilogram-force meter second squared (kgf·m·s²) is a metric unit of moment of inertia.

What is the unit of moment of inertia Mcq?

What is the unit of mass moment of inertia? Explanation: The mass moment of inertia is the product of moment of inertia and area. So L4 x L2 = L6. so its unit will be m6.

Is polar moment of inertia same as moment of inertia?

The main difference between moment of inertia and polar moment of inertia is that the moment of inertia measures how an object resists angular acceleration, whereas the polar moment of inertia measures how an object resists torsion.

What is unit of force in CGS system?

For example, the CGS unit of force is the dyne, which is defined as 1 g⋅cm/s2, so the SI unit of force, the newton (1 kg⋅m/s2), is equal to 100000 dynes.

What is the unit of radius of gyration?

meter
Radius of gyration is defined as the distance axis of rotation to a point where the total body is supposed to concentrate. SI unit of Radius of gyration is meter.

What are the units of polar modulus?

What are the units of Polar modulus? Explanation: The ratio of polar moment of inertia (J) to the radius of section(R) is known as polar modulus or torsional section modulus. Its units are mm3.

What is the SI unit of moment of inertia and radius of gyration?

Radius of gyration of a rigid body about an axis of rotation is the distance between the axis of rotation and a point at which the whole mass of the body can be supposed to be concentrated b\so that its moment of inertia would be the same with the actual distribution of mass. K = . Its S I unit is m and CGS unit is cm.

What is the unit of polar moment of inertia m2 m5 m3 m4?

Its units are mm3. 3.
