Is it possible for a first or second class lever to have a mechanical advantage less than one or for a third class lever to have a mechanical advantage greater than one?
Second class lever. . . . Always greater than 1 . Third class lever . . . . . Always less than 1 . First class lever . . . . . Can be greater than 1 or less than 1 depending on position of fulcrum.
What is the MA of a 1st class lever that is 24 cm long and the fulcrum is 0.5 cm from the resistance?
The ideal MA is 47.
The fixed point that a lever pivots around is called the?
A lever pivots on a fulcrum.
What is a fixed point on which a lever rotates?
That is the Fulcrum.
A bar that turns on a fixed point?
A lever.

What is the difference between first class second class and third class levers?
the difference is the position of the fulcrum. a first class lever has the fulcrum between the lode and applied force. a second class lever has the load between the fulcrum and applied force. A third class lever has the applied force between load and fulcrum. The load happens to be the thing that you are affecting in the system. On a seesaw the load and applied force changes as either kid goes up, but the lower kid is always the force and upper is the load with the fulcrum in the middle. this happens to be a first class lever. a second class lever could be a bottle cap opener with the fulcrum at the end the bottle cap(load) in the middle and you pushing (force) on the other. a third class lever are like tweezers with the fulcrum on the closed end, force is you pushing in the middle, and affected load is whatever you pick up. There are also compound levers like nailclippers, but by diagramming the whole system it should be pretty easy to discover that it is a first class lever. It's compund because of the use of a lever system
Where is the lever of the hammer?
The lever class of a hammer depends upon its use. If the hammer is used as a claw to remove a nail, it is a first class lever. When the hammer is used to strike a nail, it is a third class lever. There are three classes of levers. The difference between the classes lies in the position of the load, the effort and the fulcrum. When the fulcrum is between the load and effort, the object is a first class lever. If the load is between the fulcrum and effort, the object is a second class lever. A third class lever places the effort between the load and the fulcrum.

What type of lever system described as LEF?
Third-class lever
What type of lever system is described as LEF?
Third-class lever
What class lever is a spoon?
It is a third class lever machine because The effort is in between the load(food) and the fulcrum(handle)
Is a crane a class 1 lever or a class 2 lever or a class 3 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.
What is the law for a second-class lever?
the law for a second class lever is that the load is between the fulcrum and the effort
What lever class is the neck?
The neck is 1st class lever because the neck is between the head and body
What class of lever are ice tongs?
Ice tongs are actually third class lever. In a third class lever, the effort is between the fulcrum and the load.
What class lever is a wheelbarrow?
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.
