Find out about the lever, one of the most basic forms of a machine, which helps lift heavy objects with much less effort, through this fun and animated learning module. Also learn about a variety of levers from this very same module.
The lever is one of the most basic forms of a machine. Levers help us lift loads with lesser effort. Even though this looks simple there are many things going on in order to lift the object easily.
A lever can be described as a long rigid body with a fulcrum along its length.
Load :
The object you’re lifting.
Fulcrum :
Point at which the lever pivots.
Effort :
The force applied to make the object move.
We use levers in so many of our day to day activities.
Types of Lever :-
They are classified into three categories depending on the relative position of the load, fulcrum and force.
The 1st Class Lever –
where, the pivot is in between the effort and the load. E.g. Seesaw
The 2nd Class Lever –
where, the load is between the fulcrum and the effort. E.g. Wheelbarrow
The 3rd Class Lever –
where, the effort is between the fulcrum and the load. E.g Fishing rod
Activity-
Look for objects around the house that use this principle. Hint- you use one on your hands and feet regularly.

THX technology homework done
i dont like the butts on here lol
reasonably informative. could do with more information
Hello friends, good post and i am enjoying by these.
Good all time
I like it.
Well I found it okay I think it could be better with more information
thanks that helped a lot i need it for a bionic hand assignment thanks
it’s silly
Thanks Josenny! Glad to hear that 🙂
This is really helpful because I need to do a lab report for science class and this helped a lot.
thats so cool
it’s funny to me because i’m young
it was cool
