Question

WHAT IS THE DIFFERENCE BEETWEEN FIRST CLASS LEVER AND SECOND CLASS LEVER.NEED 4 ANSWERS!

Answer 1

Answer:

in first class lever the fulcrum is in the middle of the load and effort and in second class lever the load arm is smaller than the effort arm

First-class: fulcrum between the force and the load. Examples include a crowbar and a balance scale.

Second-class: load between the force and the fulcrum. Examples include a wheelbarrow.

Third-class: force between the load and the fulcrum. Examples include hammers and catapults.

A first-class lever makes a task easier by two methods:

It changes the direction of the force. The force pushes down on one end of the lever, causing the load on the other end to rise.

It changes the distance over which the force is applied in exchange for how much force must be applied. When the point where the force is applied is moved farther away from the fulcrum, the force needed to push the lever down decreases; however, the distance that it must be pushed increases.

pls mrk as brainliest

Answer 2

First class lever

The first class lever is the one you may be most familiar with. It uses a fulcrum in between, and the applied force and load are at opposite ends. The diagram at the left shows a first class lever set up to move a heavy load with a small applied force.

Second class lever

Second class lever: Second-class levers have the load between the effort and the fulcrum. A wheelbarrow is a second-class lever. The wheel's axle is the fulcrum, the handles take the effort, and the load is placed between them. The effort always travels a greater distance and is less than the load.
