    Drawing Fbd
In summary, the conversation discusses finding the tension in two separate ropes that a person is holding onto at angles of 85 degrees. The person's mass is given as 70kg and they are trying to figure out the FBD (free body diagram) for the situation. Links are provided for visual aids and resources to help understand the concept.

Homework Statement


A person is holding onto 2 separate rings and each at angle is 85 degrees. find the tension in each rope. The mass of the person is 70kg. so we know the mass of the person, and the angle of ropes, i should be able to figure it out by looking at a FBD but i don't know how the FBD would look. i just need to know what points should be taken as the square (or the dot) in the FBD, the areas where his hands meet the rings or the areas where the rope attaches to the roof

What is a FBD?

A FBD, or free body diagram, is a visual representation of the forces acting on a single object or system.

Why is a FBD important?

A FBD is important because it helps us understand the forces at play in a system and how they affect the motion of an object. It allows us to analyze and solve problems related to motion and equilibrium.

How do I draw a FBD?

To draw a FBD, start by identifying the object or system you want to analyze. Then, draw a dot or box to represent the object and label it with a letter or symbol. Next, draw and label all the forces acting on the object with arrows indicating the direction of the force. Finally, label the forces with their corresponding values and include any necessary angles.

What are some common mistakes when drawing a FBD?

One common mistake is forgetting to include all the forces acting on the object. It's important to consider all external and internal forces. Another mistake is not labeling the forces or their values correctly, which can lead to incorrect solutions. It's also important to make sure the arrows representing the forces are pointing in the correct direction.

Can I use a FBD for complex systems?

Yes, a FBD can be used for any system, no matter how complex. It may take more time and effort to identify and draw all the forces, but the principles and process remain the same. It's important to break down the system into smaller parts and draw separate FBDs for each part, then combine them to get a complete understanding of the forces at play.
