Wind Car Theory .for assignment

Click For Summary

Homework Help Overview

The discussion revolves around the concept of a "wind car," which is intended to be propelled solely by wind energy. Participants are exploring the feasibility of such a vehicle, particularly its ability to drive straight into the wind and the theoretical underpinnings that would support this idea.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants are questioning the viability of a wind-powered car driving directly into the wind, with some suggesting the need for sails to achieve forward motion. Others are seeking theoretical explanations and relevant equations to support their assignment.

Discussion Status

The conversation is ongoing, with participants expressing confusion about the concept and seeking clarification. Some have proposed ideas about using sails to generate lift, while others are still trying to understand the basic principles involved.

Contextual Notes

There is a noted requirement for equations in the assignment, and participants are grappling with the theoretical aspects of wind propulsion and efficiency without clear consensus on the feasibility of the proposed ideas.

Wind Car Theory...for assignment...

I am a student and i have to explain the wind car theory. I really need help. I need to come up with equations and real explanation. I'd be really happy if you could help me.
You can email me at : ngkho@yahoo.com.hk
Sorry again for posting my message here.
Look forward to hearing from you.
Thanks a lot.

I have absolutely no idea what "wind car theory" means! Could you give us some idea what you are talking about?
 
my topic is:
construct a car which is propelled solely by wind energy. the car should be able to drive straight into the wind. Determine the efficiency of your car.

I just need some theory of how a wind car that push by wind...thx
 
no one has an idea?
plx help...
 
What makes you think it is even possible for a car powered solely by wind to drive straight into the wind? You could get it to tack into the wind with sails but not straight into it.
 
what do u mean? i can't really understand...
is there any equations relevant to a windcar? because that assignment needs equation too...thx

I have no idea whether this could work but you might want to think about a car with two vertical sails - one on the left and one on the right. They would act like airplane wings providing "lift" normal to their surface. By rotating the sails such that their back ends extend outward from the car you can produce a component of "lift" in the forward direction with the sideways "lift" of the two sails cancelling out.
