Example of bolt property calculation:

```go

func ExampleBolt() {

	b := bolt.New(bolt.D24, bolt.G8p8)

	fmt.Printf("Bolt : %s%s\n", b.D(), b.Cl())

	fmt.Printf("%s\n", b.Do())

	fmt.Printf("Hole : %s\n", b.Do().Value())

	fmt.Printf("%s\n", b.Fyb())

	fmt.Printf("Fyb  : %s\n", b.Fyb().Value())

	fmt.Printf("%s\n", b.Fub())

	fmt.Printf("Fub  : %s\n", b.Fub().Value())

	fmt.Printf("%s\n", b.As())

	fmt.Printf("%s\n", b.A())

	// Output:

	// Bolt : HM24Cl8.8

	// For bolt HM24 hole is Ø26.0 mm

	// Hole : Ø26.0 mm

	// In according to table 3.1 EN1993-1-8 value Fyb is 640.0 MPa

	// Fyb  : 640.0 MPa

	// In according to table 3.1 EN1993-1-8 value Fub is 800.0 MPa

	// Fub  : 800.0 MPa

	// Tension stress area of the bolt HM24 is 352.8 mm²

	// The gross cross-section area of the bolt HM24 is 452.4 mm²

}

```

Example of shear resistance calculation for bolt HM24Cl5.8:

```go

func ExampleShearResistance() {

	b := bolt.New(bolt.D24, bolt.G5p8)

	sr := bolt.ShearResistance{B: b, Position: bolt.ThreadShear}

	fmt.Printf("%s\n", sr)

	// Output:

	// Calculation of shear resistance for HM24Cl5.8:

	// 	γM2 = 1.250

	// 	αν  = 0.500 - Shear plane passes through the threaded portion of the bolt

	// 	Fub = 500.0 MPa

	// 	As  = 352.8 mm²

	//	In according to table 3.4 EN1993-1-8:

	// 	Shear resistance is 70.6 kN

}
