What are the translational phenomena in CE2?

The translation phenomena in CE2 are as follows:

The translation phenomena include: the movement of the elevator, the sliding on the slide, the raising the national flag, pulling the drawer, moving the train, pushing and pulling the elevator, etc. Translation refers to moving a figure a certain distance in a certain direction in a plane. Such graphic movement is called translation.

Translation in life: the car moves in a straight line on a straight road, the opening and closing of sliding windows and sliding drawers.

Rotation in life: using a wrench to tighten a nut, a windmill to draw water, and the blades of a wind turbine to rotate around their axis.

Basic properties of translation: After translation, the corresponding line segments are parallel (or collinear) and equal, the corresponding angles are equal, and thes line segments connected to the corresponding points are parallel and equal to the translation transformation; does not change the shape, size and direction of the figure.

Translation elements: one is translation direction and the other is translation distance. Note: Graph translation is a position transformation. Translating only changes the position of the graphics, but does not change the shape and size of the graphics. The translation direction of graphics is not necessarily horizontal, but can also be vertical or diagonal. translation.

Develop knowledge:

Rotation: in a plane, the change in rotation of a figure around a fixed point by a certain angle to obtain another figure is called rotation. Rotation is a movement in which the distance from each point to the same point remains constant as the object moves, which is called rotation.rotation around this point. This point is called the center of rotation of the object. It is therefore not necessarily an axis.

Translation and rotation are for rigid bodies, so the distance between any two points on the object remains unchanged during movement and will not become its mirror image. The movement of a point can always be considered as translational movement.

Rotation Properties: Rotating a graph means that each point on the graph moves at a fixed angle around a fixed point on the plane, and the distance between the corresponding point and the center of rotation is equal.

The angle between the corresponding point and the line segment connected to the center of rotation is equal to the angle of rotation. The graphs before and after the rotation are congruent, that is, the size and shape of the graphs before and after the rotation do not change. The center of rotation is the only point that does notdon't move. The angle between a line connecting a set of corresponding points is equal to the angle of rotation.

Nuts are parts that tightly connect mechanical equipment. Nuts and bolts of the same specifications can be connected together via the threads inside. For example, M4-P0.7 nuts. can only connect with M4-P0.7 series bolts (in nuts, M4 refers to the inner diameter of the nut is about 4mm, and 0.7 refers to the distance between two threaded teeth is 0.7mm); manufactured products, such as 1/4-20 nut can only be used with 1/4-20 screws (the inner diameter of the 1/4 nut is about 0.25 inch, and there has 20 teeth in each thumb of the 20 fingers). Self-locking nuts, lock nuts, lock nuts, four-claw nuts, screw-in security nuts, thin shank connection nuts, self-locking hexagon cap nuts, screw nutsspecial anchors, lifting eye nuts with fine hexagonal crown.
