Calculus fans, come in here.....
Guys, I'm trying to calculate the area of a piston ring end cap for blowby calculations here at work....
Basically the area I'm describing is shaped like a piece of macaroni once you get down to it.
I know this is an odd shape, but I figure I'll have to do a double integral to find the area.
However, I'm having trouble calculating the arc lengths on the bottom and top of the macaroni shape.
I know arc length is based on the radius and a radian....but what's the easiest way to get that radian? I mean we're talking about an area pretty close to around .035" based on a 3.35" bore.....The radian measurement is gonna be almost nil I'd say....
I'm just trying to get a more accurate measurement of area instead of just using a rectangular shape.
