What is the name of the place were a lever pivots?
The point where a lever pivots is called the fulcrum. It serves as the fixed point around which the lever rotates when force is applied.
Is the fulcrum always located at the same place as the lever?
No, the fulcrum is not always located at the same place as the lever. The placement of the fulcrum determines how the lever functions - it can be positioned closer to the load to increase force or closer to the effort to increase distance.
Would it be easier to use a lever and fulcrum?
Depends on the job at hand. The most common use is to multiply force so you can move something that weighs more than you can lift on your own. In doing this you give up distance. Place the lever and fulcrum so that the fulcrum is close to the 'load'. When you push on the long end of the lever it moves a long distance with a small effort, The load will be lifted a shorter distance.
How is a wheelbarrow a lever?
There are 3 things in a lever. They are load,fulcrum, effort. The place where the wheel is the fulcrum, the place where we put something is load,the place we hoist the wheelbarrow is the effort so it is a second class lever.
Place 4n worth of force 0.2m from the fulcrum where would you have to place 2n in order for the lever to balance?
The force is equal to the mass times your lever arm. If 4n is placed 0.2m from the fulcrum, you have 0.8 force units on you lever arm. This would imply that a mass of 2n should be placed 0.4m from the fulcrum in the opposite direction. This would give you 0.8 force units on both sides, thereby balancing the lever.

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.
Is the fulcrum always located at the same place as the lever?
No, the fulcrum is not always located at the same place as the lever. The placement of the fulcrum determines how the lever functions - it can be positioned closer to the load to increase force or closer to the effort to increase distance.

How do you assemble a lever?
The lever itself is any rigid item, it should be long, rigid and strong. To work it needs a Fulcrum. A rock or similar thing will do. You take your Lever, place it under the object to be moved, place the lever over the Fulcrum, then push the lever to move your object.

Where would place a fulcrum of a lever if you had to lify a heavy load?
A fulcrum would be placed as close to the heavy load as possible. This minimizes the lever arm (and thus minimizes the torque) for the load while maximizing the lever arm (and thus maximizing the torque) for the force you must apply.
How are first and second class levers different?
the first class levers have the fulcrum in the middle and the resistance and effort on the two sides second class levers have the resistance in the middle and the fulcrum and the effort on the two sides
What does the lever system do?
a lever system is a type of system in which people use to gain an advantage at doing something hard. There is three different type of classes. Class 1, class 2, and class 3.Class 1 is a class in which the load is on one side of the lever system, weighing down the effort. Maybe even more than what the effort can lift. The fulcrum is located right in the middle where the point of it is. Example:A door handle. The load is the thing that is pulling it down. The effort is at the tip ,at the door keeping it nailed into the door. Finally , the fulcrum is located in the middle. Class to is quite different. The load is located in the middle, then the fulcrum on either end, and the effort on the other end.Example: a wheelbarrow. The load can be the rocks someone is lifting from a place. Then the effort is the person lifting it and lugging it across land. The fulcrum is the wheel.With class three the effort and load are switched around from class 2. Class three has the effort located in the middle with the load on either side, and the fulcrum. Example:tongs. The the load is in the middle, say containing meat. Then the effort is towards the two tips, pushing the tongs down to keep in the meat without it falling out. The fulcrum is the tip at the end where the two pieces of metal were welded together.
What class of lever is a screw driver?
A screw driver is a class 3 lever, where the effort is between the fulcrum (the place where the screwdriver pivots) and the load (the resistance of the screw being turned).
What do second and third levers both have?
the fulcrum between the effort and load B. effort applied in the same place C. two loads and fulcrums D. the fulcrum at one end of the lever
