## What type of lever is a door hinge?

A class 2 lever has the resistance or load in the middle, the fulcrum at one end and the effort at the other. An example of a class 2 lever is a wheelbarrow, where the front wheel is the fulcrum. A wheelbarrow is a second-class lever. Both a nutcracker and a hinged car door are examples of second-class levers.

## What does simple machine do?

simple machine, any of several devices with few or no moving parts that are used to modify motion and the magnitude of a force in order to perform work. They are the simplest mechanisms known that can use leverage (or mechanical advantage) to increase force.

## What type of simple machine is flagpole pulley?

A flag pole usually uses a fixed pulley to move the flag up or down. Fixed pulleys may be used in warehouses to lift loads off of trucks or trains. A fixed pulley works by changing the direction of the force and allowing you to raise things above your head (such as a flag up a flagpole).

## What simple machine is a flagpole?

A pulley is a simple machine that is used to raise and lower a load. There are many examples of pulleys in everyday life. However, a flag pole is a simple example. A flagpole uses a pulley to raise a flag far above your head.

## Why seesaw is a simple machine?

When a force is used to move something, work is done. The amount of work depends on the amount of force and the distance moved. A seesaw or teeter-totter is a simple machine found on a playground. It acts as a lever, which is simply a bar or rod that pivots (turns) on a point called a fulcrum.

## What type of lever is the seesaw explain?

Note:We have to note here that a seesaw is a case of the first class lever. The fulcrum can be placed anywhere in between the effort and the resistance in a first class lever. Crowbars, shears and pliers are also a good example of this class of levers.
