Why are machines so important?
00:00:00
Machines make our lives easier because they help us to do work.
00:00:11
There are two main types of machines, simple and complex.
00:00:19
Simple machines have few or no moving parts.
00:00:26
Complex machines have several parts and contain simple machines.
00:00:34
There are six simple machines, inclined plane, pulley, lever, screw, wedge, wheel and axle.
00:00:41
We are going to look at three of them in detail, inclined plane, pulley and levers.
00:00:57
We use inclined plane, pulleys and levers to move heavy loads.
00:01:06
A load is the weight of an object.
00:01:12
To move a load we have to apply effort.
00:01:18
Effort is the amount of force required to move the load.
00:01:25
So why are machines so important?
00:01:35
Because machines make our lives easier.
