Okay, so I’ve been messing around with engines lately, and one thing that always bugged me was figuring out piston speed. It’s not super complicated, but it’s also not something you can just eyeball. So, I decided to make a simple calculator to do the job.
First Steps: Finding the Formula
First,I gotta find how to even calculate this thing. A quick search, and bam,I found this:
Mean Piston Speed (MPS) = (Stroke in mm RPM) / 6000
Cool, cool, cool. Looks pretty straightforward. Multiply the stroke length by the engine’s RPM and then divide by * it.
Building the Calculator
I wanted something super simple, so I just use basic HTML form and Some JavaScript
- I open my code editor.
- Create some input fields: one for the stroke length (in millimeters) and another for the RPM.
- Add a button that says “Calculate.”
- And an empty paragraph where I’ll display the result.
The JavaScript Part
Now for the brains of the operation.I added javascript code.
- I grabbed the values from the input fields when you click the button.
- Then I wrote a function that takes those two numbers (stroke and RPM), plugs them into that formula I found earlier.
- Make sure all input data is correct.
- Finally, I take the result and show it the empty paragraph.
Testing it Out
I saved my file, opened it in my browser, and started plugging in some numbers. I used some specs from a random engine I found online, punched in the stroke and RPM, and hit “Calculate.”
And… it worked! The result is show in the empty *!
Final Thoughts
It is really easy and simple,but it is my record of practice.
