1. Fundamental Mechanics | 基础力学
Force: A force is a push or pull acting on an object, capable of changing its state of motion or shape. It is a vector quantity, having both magnitude and direction, measured in newtons (N).
力： 力是作用于物体上的推或拉，能够改变其运动状态或形状。它是一个矢量，既有大小又有方向，单位为牛顿(N)。
Moment: The moment of a force about a point is the product of the force and the perpendicular distance from the point to the line of action of the force. It measures the turning effect and is expressed in N m.
力矩： 力对某点的力矩等于力的大小乘以该点到力作用线的垂直距离。它衡量转动效果，单位为牛·米(N·m)。
Couple: without translation, and its moment is calculated as force × distance between the forces.
