Divide by Zero on the Friden STW10 Mechanical Calculator

CuriousMarc demonstrates what happens when attempting to divide by zero on a vintage 1956 Friden STW10 mechanical calculator.

Please, try a divide by zero! Pleeeeeease! What would happen? What if Katherine Johnson did that in the movie Hidden Figures (this is the Friden that sits on her desk)? Would it catch fire? Would the rocket trajectory go to infinity? Now you are finally going to find out. Stick to the end for a little extra, a scene from another great movie that stars the Friden. This is a Friden STW 10 from 1956.
