Question
Download Solution PDFइस्पात का बेलनाकार नमूना जिसका 11 mm का वास्तविक व्यास है, उसे विभंजन के लिए तनन परीक्षित किया गया है तथा उसमें 400 MPa का इंजीनियरी विभंजन सामर्थ्य पाया गया है। यदि विभंजन की अनुप्रस्थीय काट 10 mm है, तो विभंजन का यथार्थ प्रतिबल ________ है।
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFअवधारणा:
विभंजन पर वास्तविक प्रतिबल,
वास्तविक प्रतिबल = इंजीनियरिंग प्रतिबल × (1+ वास्तविक प्रतिबल) अर्थात्
𝜎𝑡 = 𝜎0 (1 + 𝑒)
या, \({\sigma _t} = {\sigma _f} \times \frac{{{A_i}}}{{{A_f}}}\)
गणना:
दिया गया है di = 11 mm, df = 10 mm, σf = 400 MPa
अब,
\({\sigma _t} = 400 \times {\left( {\frac{{11}}{{10}}} \right)^2}\)
∴ 𝜎t = 484 MPa.
