“gather secondary information to identify the desirable optical properties of silica, including:
– refractive index
– ability to form fibres
– optical non-linearity”
Does anyone have any information on this?
Simple if your logical
Well you have two options,
Method of sections
Method of joints
Method of sections is generally the quicker and simpler method.
Basically you imagine you cut the truss.
Every cut members now acts as an external force.
Take sum of the moments that cancels out the...
Do you find that the papers get cruddier the furthur you go back?
Is it just me or does it seem that comparing 2004 to 2001, 2001 is quite a bit more difficult, and the questions are about context that seems to be dissimilar to what you have been studying?
Wood?!?!? + Electrical conductivity
I have read that wood is relatively weak in compression because the wood fibres buckle... Anyone else concur? Also you could mention about the conductivity of the different materials, we are walking about electricity here. Especially in high power...
Too much BS!
Yeh I wish they gave harder mechanics questions, some of them are very weak! Too much BSing about societal and environmental BS, not enough calculations and theoretical work!
Probably I would say the hardest we would ever get.
It is pretty hard, I mean usually the energy questions are about lifting a load or something simple.
I got the same as you for the slope question!
I got same answer for the slope question faking made up:
3.6547555002038590652909430167106m up the slope it ends up being.
