Problems dealing with air resistance?

Click For Summary

Homework Help Overview

The discussion revolves around problems involving air resistance, specifically in the context of a helicopter's motion and forces acting on it. The original poster presents a scenario where the helicopter is moving horizontally with a given weight and lift force at an angle.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • The original poster seeks guidance on how to approach problems involving air resistance and the forces acting on a helicopter. Participants inquire about previous attempts and encourage sharing of initial thoughts.

Discussion Status

The conversation includes a mix of light-hearted responses and requests for clarification on the original poster's understanding and attempts. While some participants emphasize the importance of showing prior work, the original poster indicates they have gained clarity on their own.

Contextual Notes

There is an implied expectation for participants to engage with the problem without providing direct solutions, reflecting the forum's learning-first approach. The original poster's request for guidance suggests they are navigating the complexities of force analysis in the presence of air resistance.

Does anyone know how to solve for problems dealing with air resistance?

For example:

"The helicopter in the drawing is moving horizontally to the right at a constant velocity. The weight of the helicopter is W = 59500 N. The lift force L generated by the rotating blade makes an angle of 21.0° with respect to the vertical.

1) What is the magnitude of the lift force?

2) Determine the magnitude of the air resistance R that opposes the motion."

And show what you have already tried on this problem.

We won't do your homework for you- you're not paying us enough!
 
Ha ha...I didn't ask you to do it for me, just to give me an idea on how to do it. I got it now though, so thanks anyway.
