Over in Programmers chat we were discussing whether a gold skeleton would be feasible. That got me thinking:
If I were to build a Terminator (T-800) using pure gold as the endoskeleton, would the skeleton be able to support the weight of the terminator? If so, what type of force would cause it to deform under stress? Would it be able to handle normal human tasks such as running, walking, or jumping? What about the superhuman feats of strength the terminator performs in the movies?
For the sake of this calculation, assume a T-800 weighs an extra 30% more than a human its size. Based on what Google says Arnold's size is and a rounding slightly, that assumption is 2m tall and 150kg.
The question Stacking gold Bars indicates that gold has quite a bit of strength given its reputation as a soft metal. However, that question talks about the compressive strength: also, I am not an engineer and unable to calculate the types of stresses a skeleton would undergo and whether those would be greater than the tensile strength of gold.
Finally, assume the same or similar motors and supports: there is very little information out there, but clearly this machine is capable of supporting great loads compared to humans, throwing grown men across rooms like dolls, etc. Only the skeleton is gold: motors, electronics, etc. could remain as other metals (steel, titanium, copper).
