    Fbd Forces
AI Thread Summary
The discussion focuses on drawing a Free Body Diagram (FBD) for a metal rod with a string and mass attached, which spins parallel to the ground. Key forces to include are gravity, tension, centripetal force, and possibly elastic force. The role of gravity is acknowledged, with questions about what counteracts it, such as normal force. Participants emphasize the importance of visual representation to understand the forces acting on the mass at the end of the string. A drawing is suggested to clarify the interactions of these forces.

In the following situation, how should I draw a FBD and what forces should I include? A metal rod has a string coming out of one end. The other end of the string is attached to a small mass. The metal rod undergoes spinning action by the hand so that the string with the mass attached spins around the metal rod and is parallel to the ground. The metal rod is held in the hand perpendicular to the ground.

Could you provide a drawing please...?And what is the problem asking...?

Does gravity play a role...?

Basically the situation is, you are flinging a string with a mass at one end over your head. The strings flies around in circles kind of like a helicopter. My question is, what forces should I include in the FBD. I know there is centripetal force. There should be gravity pulling down, but what counteracts this force (a normal force?)

Elastic force,centripetal force,gravity force,and tension in the rod...What other forces would be there...?

Daniel.
 
I’m just looking for forces acting on the mass at the end of the string
 
Elastic,gravity and centripetal.But it's difficult to predict which acts how,if you don't provide a drawing ...

Daniel.
 
thanks, i'll try to get a drawing
