1, prepare the building blocks.
It is more convenient to find the building block parts by pouring the building block into the iron plate, and the building block will not be damaged or lost when it falls to the ground.
2. Build the front and chassis.
The front and chassis of a sports car are composed of four axle building blocks, three bottom plates and some parts building blocks.
3. Assemble the body and frame.
Assemble the body and frame of a sports car. The body and frame are composed of two frame building blocks and some parts building blocks.
4. Assemble tires and seats.
Assemble the tires and seats of a sports car. The tire and seat are composed of four tire building blocks and some parts building blocks.
5. Assemble headlights and luggage.
Assemble the headlights and trunk of a sports car. Headlights and trunk are composed of two headlights and a trunk building block.
6. Assemble windows and car seats.
Assemble the windows and seats of a sports car. Windows and car seats consist of a window and some building blocks.
Structure of Lego building blocks:
Most Lego bricks have two basic components-the upper protrusions and the inner holes. The bump of the building block is slightly larger than the distance between the hole and the side wall. When you squeeze the building blocks together, the protrusions will push the side walls outward and push the holes inward. This material is elastic and can keep its original shape, so the side walls and holes will squeeze the protrusions. Friction also plays a role, which prevents two building blocks from sliding apart.
The projection hole joint system uses the principle of interference fit-the tight connection between two parts based on friction without other fasteners. You can use three 2x2 boards to make a 2x2 brick, or use three 2x4 boards to make a 2x4 brick. Alternatively, 2×4 bricks can be made of 2×2 bricks and boards at the same time. The colors of raw materials used in basic Lego components are blue, black, dark gray, green, light gray, red, yellow and white.
