How to Operate the Log Spiral Calculator

I encourage anyone who wishes to play with this slide rule to read the original patent first.

It is pretty dense material; the inventor was trying to cram a lot of information into a reasonably concise document. I use a simplified version of the algorithm he uses for computation; I am leaving out details that may be quite important.

Problem 1 : Solve 95 x 7.5 ( not using the vernier )

Problem 2 : Solve 9.504 x 7.512 x 0.8701 (chain multiplication using vernier)

Problem 3 : Find the logarithm of 5. ( work with the log scale)
