what was the need for inventions of machines
Answers
Answer:
Human history is invention—to help understand and improve our world. And some of those leaps forward have been very big, both in size and historical importance. These are 35 mega machines that helped create our world, from the wheel and axle to the quantum computer .
On October 29, 2019, Leonard Kleinrock (pictured) and his team used this Interface Message Processor to send the first message to another computer using ARPANET. This moment is considered the beginning of the internet and it wouldn't have been possible without the world's first router, the IMP.
The successor to other Martian rovers like Spirit and Opportunity (RIP), Curiosity is the most advanced machine in human history to ever land on the surface of another planet and conduct scientific experiments. It's successful landing was a big win for NASA who just a year prior flew its last crewed spaceflight on American soil. It also proved that space programs can still achieve amazing things.

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.
Also, the goal of mechanics is to put up the production and earnings sales with less time and expenses. Machines are necessary in our life, because, all society needs then. Sometimes, the machines are dangerous and replaced labor but without these we cannot live; for this reason a mechanical engineer is very important.
It also takes twice as much work to lift the same object twice as far. As indicated by the math, the main benefit of machines is that they allow us to do the same amount of work by applying a smaller amount of force over a greater distance.
