Why a third class lever cannot magnify force

∙ 11y agoBecause the fulcrum is at one end of the lever and the effort is applied to the other end of the lever, with the load located between them. The effort distance is the entire length of the lever, and the resistance (load) distance is less.

∙ 7y agoThe way the second-class lever is set up (or defined), the place where the force is applied HAS TO move farther than the actual load, to get it moving. Therefore the force is less, since the force times the distance has to remain constant (assuming no friction).

What class or classes of lever always have a mechanical advantage greater than 1?
A second class lever always has a mechanical advantage greater than 1.
What makes the first class lever second class lever third class lever different?
1st order levers have the fulcrum between the load and effort arms. The mechanical advantage of these levers can be greater or less than 1, depending on the length of the arms.2nd order levers have the load portion between the effort portion and the fulcrum. These always have a mechanical advantage greater than 1. They increase the force exerted at the expense of distance.3rd order levers have the effort portion between the load portion and the fulcrum. These always have a mechanical advantage less than 1. They decrease the force exerted with a gain to the distance.
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
Why is the output force of a second-class lever always greater than the input force?
Because of the lever's mechanical advantage.
How are second class levers and third class levers similar?
Depending on condition of course. 3 boxes and taken care of $2200 easy. Dont let anyone tell you differently. These guns are extremely rare and people will tell you they are far less with the intent of making people think that are not as valuable as they are. As time goes on of course, they become more and more valuable. These were "working" guns for those serious about accuracy etc... Because of this very few of them are in excellent condition.
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.

How are first and second class levers different?
the first class levers have the fulcrum in the middle and the resistance and effort on the two sides second class levers have the resistance in the middle and the fulcrum and the effort on the two sides
Why is the output force of a second-class lever always greater than the input force?
Because of the lever's mechanical advantage.
What is the ideal mechanical advantage of a machine that changes only the direction of the input force?
There are three types of levers namely first, second and third class. First class levers can change the direction of input force.
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.

Why is a nutcracker is second class?
A lever that has the load between the fulcrum and the effort is known as a second order lever. Once again, the further away the effort is from the fulcrum and the load the greater the mechanical advantage of the lever.
Which type of lever always increases mechanical advantage?
second class lever
The mechanical advantage of a second class lever?
... is always less than 1 .
