Gears can change the speed and direction of the values being processed.
Different gear sizes can create various ratios for more complex calculations.
Role of Cams in Computation
Cams are another important mechanism in mechanical computers. They have a surface that interacts with a follower to perform calculations. The types of cams include:
Reciprocal cam
Square cam
Tangent cam
Time of flight cam
Barrel cam (used for calculating trajectories)
Understanding Differentials
Differentials are crucial for keeping track of changing values in mechanical computers. They help calculate the algebraic sum of two quantities, which is vital for accurate computations. A common type used in fire control computers is the bevel gear differential. It works with:
Spider gears
Spider shaft
End gears
