Fact of the day: Due to heat transfer, the fuel in a Formula One car can get as hot as a cup of tea!

don´t you think stressing key areas with loads they are not part of your design philosophy (ignoring loads)is somthing an engineer should avoid?
the claim was: with the engine temperatures anything between ambient and say 150°C
and made mainly from alumimium castings ,the tub made from carbonfibre-aluminium Honeycomb with Carbonfibre Not expanding with temperature there will be a mismatch at the Interface between engine and tub with the bolts providing the clamping force resulting in shearforces due to one structure altering their dimension whereas the other very likely not to grow over temps.
So we still got the engine growing in height as it reaches running temps and taking the bolts secured in the tub with it ,causing misalignment.either when cold or when hot..take your choice and hope for the best.
