The answer is the force
If the mechanical advantage of a class one lever is greater than 1, then the effort arm is longer than the weight arm. This means that a smaller input force is required to lift a larger output force, making the lever more efficient.
Yes, an arm can be considered a first-class lever when the force is applied at one end, the fulcrum is in the middle, and the weight is at the other end. For example, when lifting a load with your forearm acting as the lever, the elbow serves as the fulcrum.
the one with the fulcrum closer to the weight you needed to lift
The load or resistance is positioned between the fulcrum and the input force on a lever. The input force is applied on one side of the fulcrum, while the load is typically located on the opposite side. The lever uses this arrangement to magnify the force applied to move the load.
A lever works by using a pivot point, or fulcrum, to help lift heavy objects with less force. When force is applied to one end of the lever, it creates a mechanical advantage that allows the object to be lifted with less effort. The longer the lever arm, the greater the force that can be exerted to lift the object.

A lever at a mechanical disadvantage exerts a smaller force on the output arm than is exerted on the input arm; if you push with 10N on a lever with a disadvantage of 2, the other arm only exerts a 5N force. However, a lever with a mechanical disadvantage exerts the smaller force over a greater distance. Trebuchets are one example of a mechanically disadvantaged lever: the fairly small projectile doesn't need a huge force to propel it, and the greater distance afforded by the lever allows it to travel at great speed.

In a third-class lever, the effort arm is always shorter than the resistance arm. This mechanical advantage formula is calculated as resistance arm length divided by effort arm length. Since the effort arm is shorter than the resistance arm, this division always results in a value less than one, indicating that the force needed at the effort arm is larger than the force exerted at the resistance arm to lift a load.
A lever with a longer effort arm and a shorter resistance arm would have more mechanical advantage. In this case, if you increase the effort arm to 7 inches while keeping the resistance arm at 3 inches, the mechanical advantage would increase. This is because a longer effort arm allows for less force to be applied to overcome a greater resistance.
Yes, it is possible for a first or second class lever to have a mechanical advantage less than one. This occurs when the effort arm is shorter than the resistance arm in a first-class lever or when the effort arm is longer than the resistance arm in a second-class lever. In these cases, the force applied might be greater than the load but the lever will have a mechanical advantage less than one.
A seesaw is a type of lever because it consists of a long beam (the lever arm) that pivots on a fulcrum. When a force is applied on one end of the seesaw, it causes the other end to move in the opposite direction. This principle of force and motion is fundamental to how levers work.
