<a id="VM_Managed_DAFUL_Constraints_FrictionBall"></a>

Namespace: [VM.Managed.DAFUL.Constraints](VM.Managed.DAFUL.Constraints.md)  
Assembly: VMDCB.dll

This class is to represent the friction that use for ball.

```csharp
public class FrictionBall : FrictionRevolute, IObservableObject, IDisposableObject, ILinkable, IObject, ILinkContainer, IOwned, IHasID, IEventProvider, ILinkContainerEvent, IVerifiable

```

#### Inheritance

object ← ObservableObject ← [LinkableBase](https://github.com/AnsysVirtualMotion/DAFUL/blob/9110677a5f6a53d7604f8dfd35b4c5fceb59e8e0/DAFUL/Pre/Data/VM.Models.Pre/Models/LinkableBase.cs) ← LinkContainer ← [Friction](VM.Managed.DAFUL.Constraints.Friction.md) ← [FrictionRevolute](VM.Managed.DAFUL.Constraints.FrictionRevolute.md) ← [FrictionBall](VM.Managed.DAFUL.Constraints.FrictionBall.md)

#### Implements

IObservableObject, IDisposableObject, ILinkable, IObject, ILinkContainer, IOwned, IHasID, IEventProvider, ILinkContainerEvent, IVerifiable
