Instrcutions: 1.Draw a dashed line around the receiver. 2. Identify all the things touching the receiver 3. Identify all contact force for each thing that touches receiver. 4. Identify all field forces pushing or pulling on receiver. 5. Turn receiver into a dot and draw arrows to represent all forces you identified.

Identify your receiver with a dotted line. Be aware that if you cannot identify the agent for a force, it

probably means that there is no force! Use arrows and labels to represent the forces (like step 5, above).
