Scale Diagram (Equibrium objects)

• What is the condition for an object to be in equilibrium?

  Resultant force equals zero
• What does a scale diagram indicate about forces in equilibrium?

  The tip of the last force meets the tail of the first
• How do you represent three forces in equilibrium on a scale diagram?

  • Draw the first force
  • Draw the second force from the tip of the first
  • Draw the third force from the tip of the second
  • The diagram forms a triangle
• What shape does a scale diagram form for three forces in equilibrium?

  A triangle
• How can you verify if an object is in equilibrium using a scale diagram?

  Check if the diagram forms a closed shape
