Question

What’s the difference between a cog and a gear?

In: Engineering

Answer 1

Since it’s been explained already, the way I like to think of it as a gamer is: In the game Gears of War each solider is called a cog and as a team they’re called gears, which is actually a pretty good analogy. Basically gears are made of cogs.
