Question

List at least ten mechanical engineering products which have passed through
innovativeness​

Answer 1

Explanation:

Mechanical engineering is a very wide discipline. Its breadth is due, in part, from its need to cover the design and manufacture of almost everything in a moving system.

This ranges from a system's smallest components to the completed, sometimes enormous, machine as a whole. Throughout history, some innovations have come to define mechanics and the modern machine, the following inventions are prime examples.

These engineering innovations range from any one of the classical "simple machines" to complex concepts such as flight. This list is far from exhaustive and in no particular order.

1. The Aeolipile was an early steam reaction turbine

The Aeolipile was the world's first rotating steam engine, or more technically correct, a steam reaction turbine. It was devised by the great Heron of Alexandria in the 1st Century AD and described it in great detail in his book Pneumatica.

This relatively simple device works by heating a reservoir of water within the device to generate steam. The steam is then conducted through one of the copper supports to a pivoted brass sphere.

Once the steam reaches the sphere, it escapes through one of two nozzles at the ends of two, small, opposingly pointing arms. The escaping steam generates thrust and causes the sphere to rotate.

The basic principle is simple, but the device’s real genius is that only one of the supporting arms pass steam to the sphere (via a sleeve bearing).

This pushes the sphere against the other, ‘solid’, supporting arm, which also has a thrust bearing. The solid arm includes a conical point that bears against a matching indentation on the surface of the sphere. This combination holds the sphere in place whilst it rotates.
