The roof pitch is 32 degrees and I'm pretty sure we need at least 2400mm clearance. So I need to calculate the base of my right angle triangle with only two known angles and measurement for one side (2400). Can anybody please help? People make one happy, not houses? I do not think so. Houses are more to be trusted than people.

If you need 2400mm height and the pitch is 32 degrees then the base will be 3840.8mm The hypotenuse will be 4528.99. If you need to play around you can use this site. http://www.csgnetwork.com/righttricalc.html I am getting rusty on all this but if needed I will ask my 11 yo son. hehe Cheers Mark Re: Any mathematicians in here? 3Jul 01, 2012 7:28 pm G'Day I've done some rough calculations. Your base of your triangle should me 1248mm and your hypotenuse 2700mm.

The link I posted actually allows you to calculate different scenarios. I think your calcs result in an approx 28 degree pitch. Ciao Mark Re: Any mathematicians in here? 5Jul 01, 2012 9:23 pm It might do. I used the cosine rule from back in my Uni days i didnt even see your link there hahaha B&K House Settled Land 28/04/11 Siteworks 04/12/12 Footings 16/03/13 Slab Poured 27/03/13 Frame 22/04/13 Roof 29/04/13 Bricks 07/06/13 1st Fix 02/07/13 2nd Fix 26/07/13 Handover 18/09/13 A question. Im in Queensland and building a new home. We managed to reach practical completion 6 weeks ago but we haven't heard any date for handover yet. Who should we… 0 5800 i had the my concreters concrete right up to the fence. I have pits all along my path, so the water tends to drain away from the house and into the pits. There's only one… 7 12719 I am looking at building a house. Has anyone used Construkt Homes (based in Adelaide)? Does anyone have experience with this builder? 0 6447 |
