What else can I help you with?
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?
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.
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?
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.
What class lever is a clothespin?
When the clothespin is not clipping anything, it is a class 1 lever.When the clothespin is clipping something, it's a class 3 lever. So technically, it's both:)

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 class lever is a clothespin?

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
How do you use a lever?
It is used to lift a heavy object. Place the end of the lever under the rock. Then move a fulcrum (for example a small rock) under the lever close to where it goes under the rock. By moving your end of the lever a lot, you can make the shorter end move a little and lift a heavy weight.
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?
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.
