Overview ¶
Package section - created for calculate typically property of section
Example ¶
This a simple example
s := Ibeam{H: 0.1, B: 0.1, Tf: 0.005, Tw: 0.002}
fmt.Printf("Moment inertia of I-beam by axe X is %.4e m^-4", s.Jx())
Output: Moment inertia of I-beam by axe X is 2.3798e-06 m^-4

type Coord ¶
type Coord struct {
X, Z float64 // coordinates // meter
}
Coord - coordinate of point in plane XOZ used for triangle points
type Ibeam ¶
type Ibeam struct {
H float64 // height of section // meter
B float64 // width of flange // meter

type Plate ¶
type Plate struct {
Height float64 // height of plate // meter
Thickness float64 // thickness of plate // meter
}
Plate - typical section of plate Geomerty of plate
/\Z | +|+ | | | |--> X | | | | +-+
Example ¶
This is a simple example
plate := Plate{Height: 0.080 /* meter */, Thickness: 0.008 /* meter */}
fmt.Printf("Area of plate is %.1e m^2\n", plate.Area())
Output: Area of plate is 6.4e-04 m^2
