Multiply (the input force) x (the lever's mechanical advantage).
In a third class lever the input force is located between the output force and the fulcrum.
let the input force be F1,and the distance between point of application of input force and the lever point is x1,similarly if output force iis F2,and distance of it's point of apllication is x2,then efficiency of the lever is (F2*x2)/(F1*x1) actually F*x gives the work done,and efficiency of any machine is output work/input work
I'm not sure how to tell you how to find the output force of an object, any suggestions?
Levers are classified into three types (first-class, second-class, and third-class) depending on the relative position of the fulcrum (pivot point), the point of applied (input) force, and the location of the load (output force). In a first-class lever, the fulcrum is between the input force and the output force, and the load is moved in the opposite direction of the applied force. Placing the fulcrum closer to the load gives an advantage of force (less force needed to move the load a shorter distance), while a fulcrum closer to the point of applied force gives an advantage of distance (the load is moved a greater distance but more applied force is needed). First-class levers include a crowbar, using a hammer's claw end to remove a nail, and a pair of scissors. In a second-class lever, the load is between the fulcrum and the point of applied force, so both forces move in the same direction. Less force is needed to move the load, but the load does not move as far as the direction over which the input force must be applied. Examples include the wheelbarrow, a bottle opener, and a door on its hinges. In a third-class lever, the input force is applied between the fulcrum and the load, and both move in the same direction. The amount of applied force is always greater than the output force of the load, but the load is moved a greater distance than that over which the input force is applied. Examples include a hammer driving a nail and the forearm of a person swinging a baseball bat.

To find the output force of a wheel and axle, you can use the formula: Output Force = Input Force * (Radius of Wheel / Radius of Axle). The output force is determined by the ratio of the radii of the wheel and axle, with the input force determining the overall scaling factor.
A see-saw is a first class lever that can be found in playgrounds.
The 2nd class lever is demonstrated in drum brake systems. Each of the two brake shoes is connected to a hydraulic cylinder that applies the force to the shoes causing them to expand outwards to contact the rotating drum. The contact surface of the shoe is the load, the fulcrum is the pivot pin on the backing plate opposite the wheel cylinder. The foot pedal, itself, also demonstrates the 2nd class lever. The force is applied to the foot pad while the anchor point (fulcrum) is at the opposite end. Between the applied force and the fulcrum you will find the rod that transmits the force to the master cylinder's piston.
mechanical advantage= output force over input force
I came on here to find the answer to this question lolololololololololololololololololololololol
The MA would be 6cm because the formula to find the MA is input arm divided by output arm
My pick would be the masseter muscle and the temporalmandibular joint. Without it we would not be able to chew our food,
