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.
