A fulcrum is the turning point of a lever i.e. The hinge on a door.
It is essential to know when learning about the law of the lever i.e.
The distance from the fulcrum X force applied on the right hand side = The distance from the fulcrum X force applied on the left hand side.
IF the lever is balanced.
This can also be written as anticlockwise moments = clockwise moments.
In this case, the load is the weight being lifted or moved, and the lever is the handle or bar used to exert force on the load. The wheels act as fulcrums by providing a pivot point for the lever to lift the load.
I'm not sure in what sense that could be called a single lever...
The answer to Fulcrum's conundrum is not clear. It is a mystery or puzzle that may have multiple interpretations depending on the context in which it is presented.
There are a number of body parts that act as the fulcrums of levers. The most obvious ones are the elbow and knee joints.
The most common type of fulcrum used in daily life would have to be the "hinge". Hinges are used quite often in things like doors, making the progress of the task much easier. Most 3 year olds would be unable to open a door, but do to the fact that they are grasping the knob, which is quite far from the fulcrum/hinge... the task is much easier. Fulcrums are also used quite often in toys or machines, like a catapult or teeter-totter. Two small children lifting each other 3 feet in the air would normally seem a very insurmountable task, but due to the fulcrum in the center, it is much easier. I hope this helps. Sources: I've recently been thinking about fulcrums and their uses. Really, I'm not a crazy.

The plural of fulcrum is fulcra or fulcrums.

Gwen stefani: who who ind it up who who
Yup, they both have fulcrums
no they can br found almost anywhere but typicly they are part of the lever

ball and socket joint, sliding/gliding joint, and hinge joints
