Hi,

I have an equation for a roof loading:

=[2 x (3/2)Cos(45) x 1] x 2.25

which is:

4.24x2.25 = 9.54

When I do it, I cant make it work, instead of 9.54 I get 4.77 - what am I doing wrong:

=[2 x (1.5x0.707) x1] x 2.25

which i work as:

= [2 x 1.0605 x1] x 2.25

= 4.77

Any help would be good.
