How is mechanical advantage calculated for levers?
lenght of the effort arm divided by lenght of the load arm
What kind of lever has a fulcrum resistance arm and effort arm?
first class levers actually in front of the effort and resistance forces
How is the arm an example of a third class lever?
In third class levers effort P is in between the fulcrum F and the load W. According to the principle of lever, W/P = effort arm/load arm, here effort arm is always less than load arm.Therefore more effort has to be applied to overcome a small load. Example:- forearm used for lifting a load on the palm.
Is hammer a lever?
Yes. Your arm is the fulcrum while the effort is in the middle and the resistance is on the end
What is the formula for lever?
(AMA / IMA)100 Where AMA represents the actual mechanical advantage and IMA represents the Ideal Mechanical advantage. AMA = Fr/Fe where Fr equals the force of the resistance from the fulcrum, and Fe equals the force of the effort. IMA = De/Dr where De equals the Distance of the effort from the fulcrum and Dr equals the distance of the resistance from the fulcrum

What levers are in the arm?
3rd class levers are in your arm.
Why is the mechanical advantage of second class levers is always greater than 1?
Because the load is always between the effort and the fulcrum, so the effort arm is always longer than the load arm.
What class of lever is a radio?
Since a radio has no effort arm, no load arm, and no fulcrum, it's quite difficult to include it in the category of "levers", of any class.
How is the arm an example of a third class lever?
In third class levers effort P is in between the fulcrum F and the load W. According to the principle of lever, W/P = effort arm/load arm, here effort arm is always less than load arm.Therefore more effort has to be applied to overcome a small load. Example:- forearm used for lifting a load on the palm.
What are 10 examples for levers?
Well, there are three classes of levers. Class one levers are seesaws, where the effort force is on one end, fulcrum in the middle and object on the other end moving the opposite direction of the effort force. Class two levers are wheelbarrows, where the effort force is on one end, the fulcrum on the other and the object in the middle. Class three levers are like baseball bats, the fulcrum is on one end, the effort force in the middle and the object on the end. Other examples include: a golf club, catapult, an arm, a door, a tennis racket, a fly swatter or a stick.
Is hammer a lever?
Yes. Your arm is the fulcrum while the effort is in the middle and the resistance is on the end
Where is effort of a bottle opener?
The human hand that levers it
What is the formula for lever?
(AMA / IMA)100 Where AMA represents the actual mechanical advantage and IMA represents the Ideal Mechanical advantage. AMA = Fr/Fe where Fr equals the force of the resistance from the fulcrum, and Fe equals the force of the effort. IMA = De/Dr where De equals the Distance of the effort from the fulcrum and Dr equals the distance of the resistance from the fulcrum
Classification of levers?
There are three different Classes of levers. Class One Levers have a fulcrum in the middle. Class Two Levers have a resistance in the middle. Class Three Levers have effort in the middle.
How do levers work?
levers work by having a effort that lifts a load, and a fulcrum balances the two
