Description
"Project Learning: Making Three-dimensional Models" Projection and View PPT
The picture below is a bearing of a certain machine and its three-dimensional view. Do you know how the master worker uses the three-dimensional view of the bearing to manufacture this kind of bearing?
1. Cut it
Using cardboard as the main material, make the three-dimensional models represented by the following two sets of three views.
2. Carve a moment
According to the two sets of three views given below, make the corresponding physical model using potatoes (or radishes).
3. Get a discount
Each set of plane figures below is composed of four equilateral triangles.
(1) Which of them can be folded into a triangular pyramid? Trace the above figures on paper, cut them out, fold them into a pile, and verify your answer.
(2) Draw three views of the triangular pyramid that can be folded into the above figure, and point out how the three views reflect "the length is aligned, the height is flush, and the width is equal".
(3) If the side length of the small triangle in the picture above is 1, what is the surface area of the corresponding triangular pyramid?
4. Do it
The graphic below consists of a sector and a circle.
(1) Trace the above figure on paper, cut it out and form it into a cone.
(2) Draw three views of the cone surrounded by the above figures.
(3) If the radius of the sector in the figure above is 13 and the radius of the circle is 5, what is the volume of the corresponding cone?
5.Write
Three-view and expanded views are planar graphics related to three-dimensional graphics. Understand the relevant production practices and combine specific examples to write a short article introducing the application of three-view and expanded views.
