With reference to the effort and load , describe the
main difference between lever operating with a
mechanical advantage versus lever operating at
mechanical disadvantage

,Mechanical advantage occurs when the load is
placed closer to the fulcrum, thus requiring less
effort in the movement of the load.
Mechanical disadvantage occurs when the load is
placed farther from the fulcrum. This results in
more effort to be exerted to move the load.
Briefly describe the three categories of levers
based on the position of their fulcrum. Give an
example of each type of lever and state whether
the lever works at a mechanical advantage,
disadvantage, or both.
First class lever: scissors, and they can function at
a mechanical advantage or a mechanical
disadvantage
Second class: Wheel Barrow is a second-class lever
system, and it functions at a mechanical
advantage.
third class: Forceps (tweezers) function as a third
class lever, and they function at a mechanical
disadvantage.
