In this photo we can see a one second lever. This mechanism this fulfills the function of joining leaves.

It is a type of mechanism that consists of a closed chain that engage with pinions that are attached to the axes of the driver and driven mechanisms, this mechanism is a bicycle, through the chain you can change speed, it is a very practical mechanism.

In this picture you can see a clock, this clock is situated on the wall of my living room. All people normally have a clock on their houses. We need them to know the time.

Here we can see a clock, which is widely used throughout the world and can be found in any house, and is with which people can know the time and more things of the time.

This is a corkscrew that has more than one mechanisms. But i am going to talk about one of them. It has a second type of lever, is in the top. When you put a botle lid, you do the force in the opposite side, the resistance is in the middle and the fulcrum is in the opposite side of the force.

In this photo we can see a seesaw
It’s a type of first degree lever since at one end it has the power, in the middle the fulcrum and at the other end the resistance

in this photo you can see a lever as are the clips belonging to the third genre, I have chosen this photo since it is an example that I liked since it was explained

In this photo we can see some tweezers to pluck, these pinas are levers of third degree, that is, they have the fulcrum, then the power and then the resistance.

In this picture you can see a nail clipper . The leaves act with great force, and give rise to a combination of lever of the third gender. By Isabel María Sevilla López

Here we have two of the most typical levers of the first degree, a nail clipper and scissors. Sometimes we do not realize that technology surrounds us every day, even when we cut our hair, it is amazing.

In this photo you can see a lot of clothespins. They are a linear transmission mechanism. it's a very common object that we may not have seen in what is a mechanism.

Hello!!! In this imágenes we can se a mowing machine that serves to cut weeds anda itsmechanism consiste in sin ningún some cables to be abeto cut with ease

Hi.
here we have a lever of the second type which is about the knob of a door

Hello! Here, in this photo we can see a type of bench clamp. It uses a screw-nut system that transforms rotary movement into lineal movement. It is a very common and useful tool used to hold objects.

In this picture we can see the mechanism of an old sewing machine. The pedal transmits rotary motion to the central axis throughout pulleys with belt. Then the motion is transformed into differents types depends of the machine. In this machine, is transformed into linear motion which permits that a rigid bar moves vertically to sew

Hello there! This is my photo and you can see tongs that i  use to move the food while im cooking. They are very useful and this is a first type of lever.We cannot see all the mechanism that are surrounding us but there are more than we can see. Álvaro Cárceles

In this picture you can see pliers that are built according to the principle of the bilateral lever, which makes it possible to transform a smaller force into a greater force that acts on the jaws or on the cutting edge. The pliers refer to the first generation of levers

In this picture you can see a lower part of mi clarinet ,it is made of wood and keys,the keys make the function of a first degree lever

In this picture you can see a rotary motion mechanism composed by gears. When the black gear moves, it make that the tube rotates and it produce music with the metal bars that are next to it! It is similar to the mechanism that we saw in the video on Tuesday.

In this photo you can see a fixed pulley in a ship. There is not mechanical advantage. It helps move the sails of the ship. We can see that mechanisms are everywhere😃

In this picture you can see a corkscrew, which mechanism transforms rotary into reciprocating motion, rack and pinion.

In this photo we can see an old sewing machine that use a pulley to work  properly, like the others sewing machines, but in this one the pulley is more visible, this system also transform a circular move to a linear move.

In this picture we can see a bench clamp that my family uses to work. It has as mechanism a screw with a nut, which, when turning the iron stick, can be opened or closed.

In the video we can see a mechanism formed by several gears (plates and pinions), one chain, two pedals and one gear change. This mechanism consists in transmitting the movement and strength of the legs to the plates by means of the pedals, later, that force is sent by the chain to the pinions connected to the wheel, which moves with the intensity of the applied force. The travel of the wheel varies depending on the gear and the plate that are geared. (In this case, the gear and the plate are in the second position).

In this photo you can see a bike, is a travel method that system consists of the movement of the legs on pedals screwed to rods mounted on toothed plates and this drives, through a chain of transmission, a system of free pinion and this in turn to the rear wheel.

In this photo we can see an invention created by me. I used two DC motors putting the one with the cogwheel on top of the other. The mechanism is worm gear; is a screw thath moves a cogwheel that is set perpendicular to use the screw. The velocity is reduced but, is more powerful. JOSÉ ALEJANDRO RUIZ ARÉVALO
