For the following simple see-saw calculate
The load that could be lifted
The mechanical advantage (assum the lever is 100% efficient
In a simple see-saw, the load that could be lifted is equal to the weight of the load placed on the other end of the see-saw.
The mechanical advantage of a lever can be calculated using the formula:
Mechanical Advantage = Length of effort arm / Length of load arm
In the case of a see-saw, the length of the effort arm (where the input force is applied) is usually equal to the length of the load arm (where the load is placed). Therefore, the mechanical advantage of a see-saw is 1.
This means that a simple see-saw with a mechanical advantage of 1 is able to lift a load equal to the force applied to the other end of the see-saw.
