What will differ to the text • The descriptions will be the same • But some working out will be different • So I suggest you make a new copy on a new P10 • Then insert it into your text as a sample • Also note, my items will all appear up the top of the page, YOU will continue yours as you now know, from page to page N.

First address beam size • We assume the angle here is 45° • Therefore the 200 width will equal the 200 height • Therefore for ease of calculation, we use ½ this width and extend the base size to create a rectangle • Making it now 500mm wide for future calc’s • Similarly the central beam applies to both sides making it 600mm wide New beam width N.
