Tanks are armored combat vehicles with a closed armor protection, a rotating turret, and a track-type propulsion system. They are the main weapons for modern land warfare and are known as "land warfare". They are a type of track-type armored combat vehicle with strong direct firepower, high off-road mobility, and strong armor protection. They have excellent off-road mobility, strong armor protection, powerful firepower, and strong assault capabilities. They are mainly used to engage in combat with enemy tanks or other armored vehicles, suppress and eliminate anti-tank weapons, destroy fortifications, and eliminate enemy living forces. They can also engage in combat with enemy tanks. Tanks are generally equipped with a medium or large-caliber gun (some modern tanks can even fire anti-tank/helicopter missiles), and several anti-aircraft (anti-aircraft) or coaxial (parallel) machine guns. Most tanks use a rotating turret, but there are also a few with a fixed main gun. Tanks are mainly composed of weapon systems, fire control systems, power systems, communication systems, and armored vehicles. Now that you know what a tank is, let's get started making a wooden tank together.

Working Principle:
After assembly, the motor's driving wheel is driven by the belt wheel to rotate the auxiliary wheel, thus driving the tank model. The belt wheel transmission is driven by friction. When the driving wheel rotates, it does positive work on the belt wheel, causing its speed to increase. At the auxiliary wheel, the friction force of the belt does positive work on the auxiliary wheel, thereby making the auxiliary wheel rotate as well.

Science Project:

1. Recognize and prepare the necessary materials for the experiment.
Step 2: Install according to the instructions in the manual.
3, Install and debugging.

Scientific Principles:

Working Principle: Battery - Current - Small Motor Drives Gears to Rotate.
The principle of belt transmission is driven by friction. When the driving wheel rotates, the friction force between the driving wheel and the belt does positive work, causing the speed of the belt to increase. At the driven wheel, the friction force between the belt and the driven wheel does positive work, thereby making the driven wheel rotate. On the belt, the object is also moved by friction, which is similar to the principle of belt driving.

Science Expansion:
The invention of the tank: During World War I, both opposing forces faced a stalemate in trench warfare, which consisted of trenches, barbed wire, and machine gun nests. To break this deadlock and penetrate these defenses, there was an urgent need to develop a new type of weapon that seamlessly integrated firepower, mobility, and protection. British engineer E.D. Swinton had an accidental discovery: if a cannon or machine gun were mounted on a tractor, wouldn't it serve as a tank? In 1915, the British government adopted Swinton's suggestion and utilized automotive, agricultural, gun, and metallurgical technologies to prototype a tank. The Mark I tank was produced in 1916, with a rhomboidal exterior, rigid suspension, prominent gun mounts on the track frames on either side of the hull, and two tracks that encircle the vehicle from above. A pair of steering wheels extends behind the vehicle. The tank could carry eight crew members and came in two variants: the "Male" with two 57mm guns and four machine guns, and the "Female" with a single 6-pounder gun and two machine guns.The term 'tank' was derived from the name of the British 'Mark I' tanks, which were first used in the Somme Offensive on 15 September 1916. The term 'tank' was coined to commemorate the inventor of the tank, Sir Lionel Sir Henry Loyd, who was known as 'Tank'. The name has been in use ever since, and 'tank' is the English pronunciation of the word. In 1918, France also developed the Renault tank, which also played a role in World War I.
