Lawn Mower - Cutting Machines .. The machines we use every day and how they work

Lawn Mower:

Remember that a pencil sharpener is actually a set of spiral edges that cut as it rotates. A lawn mower is also a spiral cutting machine, but it cuts with scissors, rather than by separating with sharp edges like a sharpener.

The cutting parts of a lawn mower include a straight rectangular piece of metal, and a set of spiral pieces. As you push this machine in front of you, these spiral pieces rotate. As they rotate, each piece slides in turn around the straight, straight piece. This process results in cutting the grass that is trapped between the arms.

In order to completely imitate the grass, the spiral pieces must rotate rapidly. This rapid rotation is done by a set of wheels similar to those you see on an egg beater. There are two large wheels that rotate on the ground when you push the machine in front of you. These two wheels have teeth inside them. These teeth turn two small wheels connected to the spirals. Each revolution of the two large wheels produces many revolutions made by the small wheels, just as happens in an egg beater. These small wheels turn the spiral parts. As these spiral parts slide around the straight rod, one after the other, that pleasant sound that comes from a lawnmower is made. There are still other lawn mowers in and around your home. Find one of them and study it for yourself. The ordinary "pliers" have two flat surfaces behind the handle parts, and these surfaces are scissors for cutting wire. How do they work?!
