Levers can be all of them. A first class lever is when the pivot (funcrum) is in the middle. A second class lever has the load (resistance) in the middle, and the third class lever has the effort (force) in the middle. For example, a see-saw is a first class lever because the fulcrum is the in middle. A exmaple for a second class lever would be a can opener because the load, the can, is in the middle. And last, the thrid class lever is a arm because the effort is in the middle, because your elbow gives the effort to move the arm.

∙ 11y agoThey are the 3 types of lever a first class is where the fulcrum is in the middle a second class lever is were the load is in the middle and on a 3rd class lever the effort is in the middle. Or at least I think. The effort is well the person putting the effort. The load is the thing your carrying. I really don't know how to describe the fulcrum though.

∙ 13y agoA lever is a rigid bar that is free to rotate, or pivot, on a fixed point. The fixed point on a lever is a fulcrum.

∙ 12y agoThe distinction among the classes of levers is determined by
the physical sequence of the fulcrum, effort, and load.
When they're arranged in exactly that sequence, you've got yourself
a 3rd Class lever.

What is 1st 2nd and 3rd class levers?
Class-I . . . Effort and resistance on opposite sides of the fulcrum. Class-II . . . Both on the same side of the pivot, resistance closer to it. Class-III . . . Both on the same side of the pivot, effort closer to it.
What is the fulcrum between effort and resistance?
a 1st class lever there are 3 types of levers, 1st 2nd and 3rd class. 1st: fulcrum between effort and resistance 2nd:resistance between fulcrum and effort 3rd: effort between fulcrum and resistance Fulcrum = a pivot point on a lever. Effort = force applied on lever Resistance = load 1st example:see-saw/scissors 2nd example:wheelbarrow/car door 3rd example:someone raking/ hockey stick being usued
What class of lever is a hole punch?
If you have the fulcrum ( unmoveable pivot point) between your hand and the object you are prying, it is a 1st class. If the end of the pry bar is wedged into a fulcrum and you are trying to move something between the end of the bar and your hand, it is a 2nd class. My class used a pry bar as " a classic example of a 1st class lever"....sometimes true, but very common to use it as a 2nd class as well ( e.g. moving an alternator, etc...)

3rd class when the base is fixed to something (eg. boat or wharf). 1st class if the upper arm is rigid and lower is used to push
