For those not wanting to design their own ornaments ... imitating movements seen in mechanical gears. The self-taught designer has videos that are instructional, showing viewers how they can ...

Mechanical devices can change one form of force ... and the velocity ratio has been calculated as 3. Smaller gears with fewer teeth turn faster than larger gears with more teeth.

[Steve Mould] shows us a different take – the experimentation kit called Spintronics, which goes the mechanical way, using chains, gears, springs and to simulate the flow of current and the ...

and [What Will Makes] shows us in detail the workings of a mechanical calculator. His machine is beautifully made with gears hand-cut from plywood, and follows a decimal design in which the ...

Gears can change the direction or the speed of movement. As there are teeth around the edge of the gears they grip together and so can withstand a greater force, enabling them to move large items ...
