no it is in fact a first class lever because a see-saw is first class and this is basically a see saw except instead of a handle on each side there is 2 on one side so therefore its a first class but people think it is a second class because of scissors but this a scissors have a difference and that difference it that when using scissors when you move one handle, it moves on the other side of the fulcrum but with a can opener the handles make the actual metal that opens the can move not just the same thing but on the other side
There are three classes of levers and each represents a positional configuration of the fulcrum, the load and the force on the lever:
Class 1: The fulcrum is located between the applied force and the load
Class 2: The load is situated between the fulcrum and the force
Class 3: The force is applied between the fulcrum and the load
No its a second class lever because the fulcrum is located at one end and the force is applied to the lever arm at the other end. The "load" in this case is the can.
-- If you push down to open the soda, then your opener is a First Class lever.
-- If you lift up to open the soda, then your opener is a Second Class Lever.
-- I have never seen a Third Class lever used as a soda opener.
No. A bottle opener is an example of a class 2 lever. The load is located between the fulcrum and the force.
It's a first class lever.
Yes it is a second class lever
it is on face book
yes
A pencil sharpener is made up mostly of a helical inclined plane (screw) and a lever.
A pencil sharpener is a compound machine made up of simple machines, like the screw and lever.
A pencil sharpener is an example of a simple machine known as a wedge. The blade inside the sharpener is shaped like a wedge, which helps to cut and shape the pencil tip when it is inserted and rotated.
A pencil isn't a lever at all, unless you are using it to turn force into useful motion. If you use the pencil to write with, it's closer to being a needle reading a record, as it is dragged across a surface, leaving graphite which has broken off of the main core on the paper. For a first class lever, think of a see-saw. For a second class lever, think of a wheelbarrow. For a third class, think of a pair of nail clippers, or of your forearm.
first class lever
First class lever
First Class LeverIt is a First class lever.
ummm absolutely none its just wood with graphite inside i think you haave got a bit confused....
it is a 2nd class lever
it is a first class lever
3rd class lever
A crane is a first class lever when it is winching in or out the rope attached to a load. The crane becomes 3rd class lever when it's boom is luffing, i.e. it is being lowererd or raised.
