"Graduation (Friends Forever)" And so we talked all night about the rest of our lives Where we're gonna be when we turn 25 I keep thinking times will never change Keep on thinking things will always be the same But when we leave this year we won't be coming back No more hanging out cause we're on a different track And if you got something that you need to say You better say it right now cause you don't have another day Cause we're moving on and we can't slow down These memories are playing like a film without sound And I keep thinking of that night in June I didn't know much of love But it came too soon And there was me and you And then we got real blue Stay at home talking on the telephone And we would get so excited and we'd get so scared Laughing at ourselves thinking life's not fair And this is how it feels As we go on We remember All the times we Had together And as our lives change Come whatever We will

DETAIL PROFIL UJI TARIK Data yang didapatkan dari uji tarik dapat digeneralisasi seperti di bawah ini.      Gambar Profil data hasil uji tarik Deformasi plastis ( plastic deformation ) Yaitu perubahan bentuk yang tidak kembali ke keadaan semula. Pada gambar yaitu bila bahan ditarik sampai melewati batas proporsional dan mencapai daerah landing. Tegangan luluh atas σuy ( upper yield stress ) Tegangan maksimum sebelum bahan memasuki fase daerah landing peralihan deformasi elastis ke plastis. Tegangan luluh bawah σly ( lower yield stress ) Tegangan rata-rata daerah landing sebelum benar-benar memasuki fase deformasi plastis. Bila hanya disebutkan tegangan luluh (yield stress), maka yang dimaksud adalah tegangan ini. Regangan luluh εy ( yield strain ) Regangan permanen saat bahan akan memasuki fase deformasi plastis. Regangan elastis εe ( elastic strain ) Regangan yang diakibatkan perubahan elastis bahan. Pada saat beban dilepaskan regangan ini akan k
