During the course of my average day at work I’m constantly doing little calculations for some aspect of a design. Most recently I was selecting Pneumatic cylinders for a project and had to constantly calculate the cross sectional area for each cylinder so I could determine the force it would output at a given pressure. I did what any self-respecting engineer would do and fired up excel and made a spreadsheet. In this spreadsheet I made a column of cylinder diameters and another of pressure and from there was able to calculate the force each cylinder would produce. Instead of recreating this spreadsheet every time I was going to need to select a pneumatic cylinder, I decided to create a cylinder calculator.
