moment专业名词

1. Moment of inertia: a measure of an object's resistance to

changes in its rotation speed. It depends on the shape and mass

distribution of the object.

2. Moment arm: the perpendicular distance from a point of interest

to the line of action of a force vector. It determines the torque

exerted by the force.

3. Moment (physics): a measure of the rotation experienced by an

object around a fixed point or axis, calculated as the product of the

force and the distance from the point or axis.

4. Moment (probability theory): a summary statistic used to

describe the shape, center, and spread of a probability distribution.

5. Moment (statistics): a summary statistic used to describe the

shape, center, and spread of a data distribution.

6. Moment generating function: a function used to uniquely

determine the probability distribution of a random variable.

7. Moment resistance: the ability of a structural member to resist

external moments or bending moments without failure.

8. Moment distribution method: a structural analysis technique

used to redistribute moments and forces in a statically

indeterminate structure.
