The lever effect for lifting refers to using a lever to reduce the amount of force needed to lift a heavy object. By increasing the distance between the pivot point (fulcrum) and the object being lifted, less force is required to lift the object. This principle is based on the relationship between the distance from the fulcrum to the applied force (effort) and the distance from the fulcrum to the object being lifted (load).
The most important part of a lever is the fulcrum, which is the fixed point around which the lever rotates. It determines the mechanical advantage and efficiency of the lever in moving or lifting objects.
A lever allows you to apply force over a longer distance than directly lifting the block, reducing the amount of force needed to lift it. By using a lever, you can amplify the force applied to lift the block, making it easier to lift.
That is not an example of a 1st class lever. In a 1st class lever, the fulcrum is between the effort and the load, such as a seesaw. An example of lifting your chin off your chest, like during a sit-up, would be a 3rd class lever, where the effort is between the fulcrum and the load.
Yes, the spot where a lever turns is called a fulcrum. It is the point where the lever pivots or moves around to create mechanical advantage in lifting or moving objects.
Common uses of a lever include opening a door, using a seesaw, lifting heavy objects with a crowbar, and using scissors to cut paper. Levers are simple machines that provide a mechanical advantage to make lifting or moving objects easier.

You haven't mentioned whether the effort force of 10n is successfully lifting the load of 100n. If it is, then the mechanical advantage of the lever is 10 or more. If the load is just sitting there and not lifting, then the MA of the lever is less than 10. Note: None of this analysis has any value unless the lever itself is massless.
A dumbbell is considered a type of lever, specifically a class 1 lever. In this case, the fulcrum is the point where the dumbbell is held, the effort is the force applied by the person lifting the dumbbell, and the load is the weight of the dumbbell itself. By applying force at one end of the lever (lifting the dumbbell), the load (weight) at the other end can be moved, making it easier to perform exercises and build strength.

Using a lever to lift a stone provides mechanical advantage, allowing you to lift heavier loads with less effort. It also allows for precise control over the lifting process. Lastly, a lever can be easily adjusted or used in various positions to suit different lifting needs.
Yes. If it takes a force of 80 lb to to move the lever, that would be the same as lifting 80 lb. Unless you can apply the force by, for example, standing on the lever and letting your weight provide the force instead of using your muscles.
The pivot point of a lever is called the fulcrum.
