:moon: Right!

This time im looking how wind speed relates to a load figure?!

Basically so i can calculate if the something im designing for a uni project will hold up in 40 km/h of wind!

Many thanks in advance!

Theres a formula for for losses due to air resistance of a vehicle which i imagine would stand true, except the wind speed should be taken into account, not the vehicle speed.

You will need to know a Cd value though, but a flat sheet is 1.

Do some research you lazy fecker, its not that hard! Get your books out!

You talking flight principles or hurricane style forces?

If flight then look here....http://www.auf.asn.au/groundschool/index.html#weight

If hurricane style stuff then its down to the size of the exposed surface and how wind moves around it.......

To test aerodynamic resistance why not set up a hairdryer and spray in the direction of the flow some aerosol....or safer still some cigarette smoke.....that way you see how the air flows around the object...

There will be a threory of weight to wind speed which probably you will find in the properties of free fall or huricane research...

Am i on the right page? Not that i know anything about this stuff or anything.... :bandit:

Mate, working out the force is easy....the hard bit is figuring out if/where/how you think it will break under that load.
