As part of a question on axial load I need to simplify two equations in terms of P ([1] and [2]).(adsbygoogle = window.adsbygoogle || []).push({});

In the above you can see how F_{BA}and F_{BC}were simplified to 0.8081P and 0.7143P respectively.

I understand both the section prior to this and the one after, though I do not understand how this simplification was carried out.

Any help would be greatly appreciated.

Thanks.
