Answers
Answer:
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 are helpful to humans in many ways. They reduce the workload of humans. They make our lives easier and stress-free. We can say that we're surrounded by machines.
Even some industries are now hiring robots (Machines) to reduce the workload on their employees.
Machines don't need break, they work 24/7 without taking any salary so these are becoming the first priority of probably each and every business.
But when we see the negative effects, machines are not worth replacing employees. When machines will take over the businesses, the employees there will be fired and then they will become unemployed. Unemployment is already a major problem in India, imagine the rate of it when machines come.
Hence, machines make our lives easier but we also have to see the other side as well.
