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.
How is a wheelbarrow a lever?
A wheelbarrow is a lever because the wheel acts as the fulcrum, the handles provide the effort force, and the load (materials being carried) is placed between the effort force and the fulcrum. When you push down on the handles, the wheelbarrow rotates around the wheel, making it easier to lift and move heavy loads.
Under which class of lever would you place cantilever is it first class second class or third class?
A cantilever is an example of a first-class lever, where the fulcrum is located between the effort and the load. This means that the force is applied on one side of the fulcrum and the load is on the other side.
Place 4n worth of force 0.2m from the fulcrum where would you have to place 2n in order for the lever to balance?
You would need to place the 2N weight 0.4m from the fulcrum in order for the lever to balance. This is because the lever is in equilibrium when the clockwise moment (force x distance) equals the counterclockwise moment. So, 4N * 0.2m = 2N * 0.4m.
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).

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.
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.
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
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).
How do you use a lever?
To use a lever, place the object to be moved on one end of the lever (load), and apply a force on the other end (effort). The pivot point or fulcrum acts as the point of support for the lever and allows for the object to be lifted or moved with less effort. By adjusting the distance of the load and effort from the fulcrum, you can increase mechanical advantage and make it easier to lift heavy objects.
What do second and third class 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
Would it be easier to use a lever and fulcrum?
Yes, using a lever and fulcrum can make lifting heavy objects easier by providing a mechanical advantage. By applying force at the right point on the lever, you can lift heavier loads with less effort than lifting directly.
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
