Answer 1

Answer:

1 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. ... The simple machines are the inclined plane, lever, wedge, wheel and axle, pulley, and screw.

2 The basic purpose for which most simple machines are designed is to reduce the effort (force) required to perform a simple task. To achieve this, the force applied must act over a longer distance or period of time resulting in the same amount of work being performed by a smaller force

3 Here are the safety measures in using simple machines:

Use the right type of simple machine for the right job.

Secure pulleys before using them.

Simple machines that are sharp should be handled with care.

Do not leave sharp objects exposed. ...

Keep sharp and pointed tools in a box.

Never play with sharp and pointed tools

4 advan tage

Simple machines are useful because they reduce effort or extend the ability of people to perform tasks beyond their normal capabilities. Simple machines that are widely used include the wheel and axle, pulley, inclined plane, screw, wedge and lever

Machines help man to reduce his job. Machines reduce the time taken to do a job. Machines can do the job of more persons in less time

Answer 2

$\huge\color{cyan}\boxed{\colorbox{black}{Answer}}$

1) A machine with few or no moving parts that is used to make work easier (provides a mechanical advantage). For example, a wedge, wheel and axle, lever, inclined plane, screw, or pulley.

2) The basic purpose for which most simple machines are designed is to reduce the effort (force) required to perform a simple task. ... Screws, levers and inclined planes are designed to increase the distance over which the reduced force acts so that we can push or pull with less effort.

3) The safety measures in using simple machines:-

• Use the right type of simple machine for the right job.
• Secure pulleys before using them.
• Simple machines that are sharp should be handled with care.
• Do not leave sharp objects exposed.
• Keep sharp and pointed tools in a box.
• Never play with sharp and pointed tools.

4) => Advantages of simple Machines:-

Simple machines are useful because they reduce effort or extend the ability of people to perform tasks beyond their normal capabilities. Simple machines that are widely used include the wheel and axle, pulley, inclined plane, screw, wedge and lever.

=> Disadvantages of simple machines:-

The major disadvantages of machines are discussed further. Machines are expensive to buy, maintain and repair. A machine with or without continuous use will get damaged and worn-out. Machines are very expensive when they are compared with human labour that is cheap and available.
