1st class lever
3rd class lever
Usually it is a first class lever, though it depends entirely on the specific application. What I first think of when someone tells me to "bring me that lever over here" is a spud bar or crowbar, which are used with the fulcrum between force and load. But if a wheelbarrow would be more appropriate, that person would be asking for a second class lever, or if a stapler is more appropriate to the situation then they would be asking for a third class lever. The following link has a much better discourse on levers than I can do.
between the effort and resistance forces :))
every lever has a fulcrum
The first-class lever
Between the effort and the load.
That's a Class-1 lever.

In a First Class lever, the fulcrum is between the effort and the load.
A First Class lever is one in which the fulcrum is locatedbetween the effort and the load.A Second Class lever is one in which the load is locatedbetween the fulcrum and the effort.A Third Class lever is one in which the effort is locatedbetween the fulcrum and the load.
The mechanical advantage of a First Class lever is Distance of the effort from the fulcrum/Distance of the load from the fulcrum
Ice tongs are actually third class lever. In a third class lever, the effort is between the fulcrum and the load.
No. In a first class lever, the fulcrum is in the middle. Such as see-saws.
In a First Class lever, the fulcrum is between the effort and the load.
That depends where the fulcrum is. The closer the fulcrum is to the load (one-class lever), the easier.
a class two lever has fulcrum at one end and the load in center
A First Class lever is one in which the fulcrum is locatedbetween the effort and the load.A Second Class lever is one in which the load is locatedbetween the fulcrum and the effort.A Third Class lever is one in which the effort is locatedbetween the fulcrum and the load.
The mechanical advantage of a First Class lever is Distance of the effort from the fulcrum/Distance of the load from the fulcrum
A see-saw is a fulcrum type of lever.
Ice tongs are actually third class lever. In a third class lever, the effort is between the fulcrum and the load.
No. In a first class lever, the fulcrum is in the middle. Such as see-saws.
A wheelbarrow is an example of a second-class lever. The load is situated between the fulcrum and the force. The wheel-barrow is a 2nd class lever as the resistance is in between the force (effort) and the axis. A wheelbarrow is a class 2 lever. The fulcrum is the wheel or wheels in front of the wheelbarrow. You stand behind the wheelbarrow. The load is between you and the fulcrum.
It is (distance from fulcrum to effort)/(distance from fulcrum to load).
Pliers are a first class lever so the fulcrum is in the center.
Class 3.
