What else can I help you with?
Where do you place the fulcrum to get the most lifting power from a simple lever?
A lever's mechanical advantage is the ratio of the effort arm to the load arm. The shorter the load arm, the greater the lifting power, so the closer the fulcrum is to the object being lifted, the better.
How can you make it easier to lift the load when the load is at a constant position on the lever arm?
when the load is at a constant position on the lever arm, how can you make it easier to life the load?
Is it easier or more difficult to lift a load when the fulcrum is close to the load?
It is easier to lift a load when the fulcrum is close to the load because the lever arm is shorter, reducing the amount of force needed to lift the load. This principle is known as the Law of the Lever.
Lifting your chin off your chest is an example of a 1 st class lever?
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.
What is effort force on a lever?
The effort force on a lever is the force applied to the lever to move an object or overcome a resistance. It is the force exerted by the person or machine using the lever to achieve a desired outcome, such as lifting a heavy object or moving a load. The effort force, combined with the lever's mechanical advantage, helps to make tasks easier and more efficient.
How does lever help make work easier?
a lever makes work easier in the sense that it help carry a heavy load from the ground in a process called lifting!
Where do you place the fulcrum to get the most lifting power from a simple lever?
A lever's mechanical advantage is the ratio of the effort arm to the load arm. The shorter the load arm, the greater the lifting power, so the closer the fulcrum is to the object being lifted, the better.
When the load is at a constant position on the lever arm how can you make it easier to lift the load?

What simple machine is a dumbell?
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.
What is the mechanical advantage of a lever with a load of 100n and an effort force of 10n?
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.
Is it easier or more difficult to lift a load when the fulcrum is close to the load?
It is easier to lift a load when the fulcrum is close to the load because the lever arm is shorter, reducing the amount of force needed to lift the load. This principle is known as the Law of the Lever.
How efficient is a lever?
That depends where the fulcrum is. The closer the fulcrum is to the load (one-class lever), the easier.

How does a first-clss lever help you lift a turkey?
A first-class lever consists of a fulcrum positioned between the effort and the load. When lifting a turkey, you can place the turkey on one end of the lever (the load) and apply force on the opposite end (the effort), while the fulcrum acts as the pivot point. This setup allows you to amplify your force, making it easier to lift the turkey with less effort than lifting it directly. By adjusting the distance from the fulcrum, you can further increase your mechanical advantage.
