Equilibrium Question -- Thrust versus Lift....

Click For Summary

Homework Help Overview

The discussion revolves around a physics problem related to forces acting on an aircraft, specifically focusing on thrust, lift, weight, and resistance. Participants are exploring the relationships between these forces in the context of equilibrium.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants are attempting to determine the values of lift and resistance based on given thrust and weight. Some question whether additional information is needed to solve the problem accurately, particularly regarding the state of the aircraft (equilibrium or acceleration).

Discussion Status

The conversation includes varying interpretations of the problem, with some participants suggesting that lift equals thrust and resistance equals weight, while others emphasize the need for more context. The discussion is ongoing, with no clear consensus reached.

Contextual Notes

One participant mentions an angle of 30 degrees, which may influence the calculations, but the implications of this angle are not fully explored in the discussion.

Homework Statement


Given:
Thrust: 103000 N
Lift = ?
Weight = 86500 N
Resistance = ?

Homework Equations


I'm just to figure out the value of resistance and lift.

The Attempt at a Solution


I can't seem to figure out a way to find out resistance, but with lift I believe it has something to do with the weight.

Maybe I'm missing something, but the answer appears trivial to me, and this is not an Advanced problem. The "Lift" is equal to the thrust and the "Resistance" is equal to the weight. Perhaps someone else will supply something different from that, but that is what I think the answer would be.

Technically you cannot solve this problem without more information. Is the aircraft flying "in equilibrium" or is it accelerating?

I forgot to mention that there was an angle of 30 degrees. Just had to use cos 30. Thanks for taking the time to reply back! No help needed anymore.
