The forces of interest are all of the forces that act directly on the object of interest. The forces that act directly on point C are the three tensions in the three ropes. Although the crate's weight creates the tension in the rope between the crate and point C , the weight does not act directly on point C and is, therefore, not included in the free-body diagram.
Draw your vectors starting at point C . The orientation of the vectors will be graded. The exact length of the vectors will not be graded. ANSWER:

Part B As shown, a light hangs from a chain that is connected to a ring held in place by two ropes. One rope is attached directly to a tie-down on a wall, and the other rope passes over a pulley that is mounted on the ceiling before being attached to a tie-down on the opposite wall. Complete the free-body diagram of the light by drawing the forces that act on it.
Hint B.1
How to approach the problem
When drawing the free-body diagram, consider the object of interest as a particle and follow these steps: Determine the cut that isolates point D from its surroundings. Identify the forces acting on point D . Include the identified forces in the free-body diagram. Hint B.2
Determine the cut that isolates the light
The diagrams below show a dashed circle that isolates different parts of the system. Which cut would best isolate pointD ?
Hint B.3
Identify all the forces that act directly on the light
Based on the diagram that isolates the light from the remainder of the system, what forces should be included in the free-body diagram? ANSWER:
Select all that apply. ANSWER:
, the tension in the rope between the pulley and the wall , the tension in the rope between the ring and the wall
