Area of opening window

[Maybo]

Hi,

I hope somebody can help?

The question is if I have an opening window that measures 0.35m x 1.495m what will be the area of the pivoting element of the window expressed as a percentage of the overall plane area of the opening assuming the window can swing open by 70^o ?

Thank you.

We can help with the math stuff, but you'll need to provide the construction stuff. How does the pivoting element relate to the area of the window? Is it a fixed size, or does the size vary in some manner? How does the angle come into play?

When you reply, please include your work and thoughts thus far. Thank you!

Hi. Thanks for responding.

The window is to pivot along one edge (1.495m high) so the pivoting element applies to the window as a whole swinging open as an edge hung one would do. My thoughts so far are that viewed in plan view I will have the window width (radius?) of 0.35m creating an arc from say 0^o around to 70^o to which it is restricted. Am I correct in saying that this will then form the sector of a circle [1/2 x arc x angle in degrees] resulting in 1/2 x 0.35 x 70 = 0.075m²? If I then multiply that by the height I will get 0.075m² x 1.495m = 0.112125m³ and I'm now in m³ but the window area (1.495m x 0.35m) is in m²? To calculate the opening area as a percentage of the plane area of the window I need to be in m2 and it's this that's throwing me.

I hope this makes some sense???
