Study Notes
Simple Machines
- A wheel with a rod, called an axle, through its center is an axle and wheel simple machine.
Types of Simple Machines
- An object with at least one slanting side ending in a sharp edge is a wedge simple machine.
- A lever is a simple machine that pivots around a fixed point to apply force or lift loads.
- An inclined plane is a simple machine with a sloping surface used for raising heavy loads.
- A pulley is a simple machine with a grooved wheel and a rope, used for lifting or moving heavy objects.
Functions of Simple Machines
- The primary role of a wheel and axle is to reduce friction and make it easier to move heavy loads.
- A pulley is used to change the direction of a force, making it easier to lift or move objects.
- The primary role of a wedge is to split or cut objects, or to hold objects together.
- A screw is a simple machine with threads wrapped around a cylinder, used for lifting, moving, or holding objects.
