Please help! iam working on the following question, please dont just tell me the answer, i really need to know how to work it out, many thanks. Destructive tensile testing on samples of two ceramic fibre composites have been used to determine their ultimate tensile stress $($UTS$).$ Sample $1$ has been in use for several years $($under cyclic loading$),$ Sample $2$ has just been freshly manufactured. The test results are shown in the table $1.$ i$.$ The test shows that Sample$1$ has degraded considerably, discuss and explain the possible cause of degradation. ii$.$ Sample $2$ is also lower than the expected theoretical value, what possible factors may have contributed to the lower UTS?$\backslash$table$[[$Test$,\backslash$table$[[$UTS$],[$MPa$]]],[$Sample $1,94],[$Sample $2,190],[$Theoretical Value,$210]]$
