Question
Download Solution PDFA और B पर तय की गई 5 m की एक बीम 'A' से 2 m पर 50 kN के बिंदु भार का वहन करती है। क्रमशः आलंब 'A' और 'B' पर निश्चित छोर आघूर्ण क्या हैं?
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFअवधारणा:
जब एक बीम को बिंदु भार और स्पष्ट भारण जैसे कि uDL के अधीन किया जाता है तब निश्चित छोर आघूर्णों को नीचे दिया गया है:
गणना:
दिया हुआ:
a = 2m
b = 3m
L = a + b = 5m
P = 50 kN
\(M_{AB}^F = - \frac{{P{b^2}a}}{{{L^2}}} = - \frac{{50\; \times\; {{\left( 3 \right)}^2}\; \times \;2}}{{{{\left( 5 \right)}^2}}} = - 36\;kNm\;\left( \uparrow \right)\)
-ve चिह्न का अर्थ है कि \(M_{AB}^F\) वामावर्त में है
\(M_{AB}^F = + \frac{{P{a^2}b}}{{{L^2}}} = \frac{{50\; \times \;{{\left( 2 \right)}^2}\;\times\; 3}}{{{{\left( 5 \right)}^2}}} = + 24\;kN\;M\left( \downarrow \right)\)
