Advantage of third class lever?
'Mechanical Advantage' of a 3rd class lever is always less than 1. Force on the resistance is less than the effort force. Distance moved by the load is greater than distance moved by the effort. Eg: fishing pole.
The mechanical advantage of a second class lever?
... is always less than 1 .
Mechanical advantage of a 3rd class lever?
always less than 1
Why is it useful to use a third class lever with the machanical advantage less then 1?
Here we don't always depend on the number but only the convenience of handling mechanically. First class. Fulcrum in the middle (scissors) Second class : Load is in the middle (nut cracker) Third class: Power is in the middle (forceps)
Does a second class lever always has an input force that is less than the output force?
Yes.
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.
How does a carjack makes work easier?
This isn't that kind of carjack that you guys think it is, it a kind of tool for a car. It makes work easier because you can use it as a lever. You can use it as any kind of lever, a first class lever, a second class lever, ora third class lever. It works better as a third class lever. It works better as a third class lever because your using less work. Less work is being done with a third class lever because of he distance. The more the distance, the less force you need. Also, the more the distance, the less heavier it is.
MA of a first class lever?
Class-III Lever . . . MA always less than 1. Class-II Lever. . . . MA always more than 1. Class-I Lever . . . . MA can be 1, more than 1, or less than 1.
Advantage of third class lever?
'Mechanical Advantage' of a 3rd class lever is always less than 1. Force on the resistance is less than the effort force. Distance moved by the load is greater than distance moved by the effort. Eg: fishing pole.
How is machanical advantage calculated for a third class lever?
Mechanical advantage: Class-I lever . . . can be any positive number Class-II lever . . . always less than ' 1 ' (and more than zero) Class-III lever . . . always more than ' 1 '
Mechanical advantage of a 3rd class lever?
always less than 1

Does a second class lever always has an input force that is less than the output force?
Yes.
Why is the output force always less than the input force in the third class lever?
Because the output distance is always greaterthan the input distance,and the product of (force) x (distance) is nearly the same on both ends.
Why is the output force always less than th input force in third class lever?
Because the output distance is always greaterthan the input distance,and the product of (force) x (distance) is nearly the same on both ends.
Why does second class levers have a mechanical advantage greater than one?
Why a third class lever cannot magnify force
