Simple machines are useful because they can make a physical job easier by changing the magnitude or the direction of the force exerted to do work.

Have you ever tried to unscrew a nut, bolt, or screw from something with your bare hands and discovered that it was just too tight to loosen even if you had a good grip?

You got the proper tool, such as a screw driver or wrench, and unscrewed it!

Why is it that it's so easy to unscrew with a tool when you can't with your bare hands?

The wrench and screw driver are examples of a wheel and axle, where the screw or bolt is the axle and the handle is the wheel. The tool makes the job easier by changing the amount of the force

you exert. Wheel Axle All of the simple machines can be used for thousands of jobs

from lifting a 500-pound weight to making a boat go. The reason why these machines are so special is because they make difficult tasks much easier.
