Homework Help Overview

The discussion revolves around a vehicle dynamics problem involving the calculation of a car's roll while navigating a banked turn. The scenario includes specific parameters such as the banking angle, velocity, and track width, but lacks the radius of the turn, which is crucial for analysis.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants explore the need for the radius of the turn to calculate centripetal force and question the implications of missing information. There is also discussion about the role of track width in determining the radius.

Discussion Status

The conversation is ongoing, with participants raising questions about the problem setup and the necessary information for calculations. Some guidance has been offered regarding the relationship between track width and radius, but no consensus has been reached on how to proceed without the radius.

Contextual Notes

Participants note that the problem may be incomplete due to the absence of the radius, which is essential for solving the dynamics involved. There is also uncertainty regarding the interpretation of "track width" and its relevance to the problem.

I want to calculate the roll of a car going around a turn that is bank 24 degrees at a velocity of 160mph and a track width of 50 inches. TO be honest I am not sure where to start with the data I am given. It would seem to be a simple dynamics problem

I believe you need to know the radius of the turn to calculate the centripetal force. If you know that, then you can figure everything else out.
 
I thought something about that, but I don't have a radius. The professor did make up this problem, so maybe he forgot to tell us all the info.
 
Without the radius, you cannot solve the problem. The "track width" seems to be an additional part of the radius. If the radius is the distance from the center of the course to the inner edge of the track, then the track width multiplied by the cosine of the banking angle will give the extra component of the radius which is required for further calculations.

That, or the professor was not specific in what the "track width" is.
 
what do you mean by
"I want to calculate the roll of a car"?
is it the net acceleration you want? or all the forces acting on it? or?...

sorry I am not following you.
