The adverb relating to advantage is "advantageously" - pronounced with a stress on the third syllable.
One third didn't finish.

Third time's the charm.
The ideal mechanical advantage of a third-class lever is always less than 1. These levers allow for increased speed and range of motion at the expense of force output.
In a second-class lever, like the effort between the strongman and the turkey, the load is between the fulcrum and the effort. This arrangement allows for more mechanical advantage compared to a third-class lever, where the effort is between the fulcrum and the load. In third-class levers, the effort required to move the load is greater because of the reduced mechanical advantage.
The mechanical advantage of a third-class lever is always less than 1, meaning that the output force is greater than the input force. Third-class levers are designed to increase speed or range of motion rather than force. Examples of third-class levers include tweezers and forearm muscles.
There are three types of levers namely first, second and third class. First class levers can change the direction of input force.
First-class levers and third-class levers tend to be force multipliers. In a first-class lever, the fulcrum is between the effort (applied force) and the load, allowing for mechanical advantage. In a third-class lever, the effort is applied between the fulcrum and the load, amplifying the input force.
Most of the levers in the body are third-class levers because they prioritize speed and range of motion over force production. These levers allow for quick and efficient movement by placing the effort arm (muscle force) between the fulcrum and the resistance (load). While they do not provide a mechanical advantage in terms of force, they are well-suited for precise and coordinated movements required in activities like sports and everyday tasks.
In first-class levers, the fulcrum is located between the effort force and the resistance force, providing a mechanical advantage that can increase force or distance. In second-class levers, the resistance force is between the fulcrum and the effort force, allowing for a greater mechanical advantage in terms of force but not distance. In third-class levers, the effort force is applied between the fulcrum and the resistance force, offering a mechanical advantage in terms of distance but not force.
The key difference between the three classes of levers is the relative positions of the effort, load, and fulcrum. In a first-class lever, the fulcrum is between the effort and load. In a second-class lever, the load is between the fulcrum and effort. In a third-class lever, the effort is between the fulcrum and load.
To increase the mechanical advantage of a third-class lever, you can adjust the distances between the effort force, the fulcrum, and the load. By increasing the length of the effort arm or decreasing the length of the load arm, you can increase the mechanical advantage.
Levers are used to multiply the mechanical force applied to a load.
In a typical lever system, the input force is applied to one end of the lever, called the effort arm, which then moves the other end, known as the resistance arm, to lift or move the load. Lever systems work on the principle of overcoming resistance with a mechanical advantage provided by the lever's design. The location of the pivot point or fulcrum determines the class of lever being used, with three main classes: first-class levers, second-class levers, and third-class levers.
